It is difficult to imagine how to use an interior door without such a mandatory attribute as a handle. At first glance, its installation may seem complicated. However, with a serious approach to the task, the availability of the necessary tools and materials and proper organization you can handle the task yourself. In the presented material we will consider how the handle is installed on interior door.

Types of handles

There are several types of handles that are suitable for inserting into an interior door:

• rotary;
• with a push mechanism;
• without locking mechanism.

Stationary handles, which do not have a mechanical part, allow you to open the door under the influence of pull. As for push-pull systems, the latter have a lever-style shutter. In the process of pressing such a handle, the lock tongue moves inward, which allows you to open the door.

What is a lock for an interior door with an oval handle? Installing such a system allows you to open the door without pressing the lever. Thanks to round shape handles, the operation is carried out by turning the holder. The design may include a locking button, which allows you to fix the tongue of the locking mechanism. This way you can lock the interior door from the inside.

Tools and materials

What does installing handles on interior doors require? During self-installation The following tools may be needed:

• pencil;
• manual or electric drill with an attachment in the form of a feather drill;
• screwdriver;
• chisel for woodworking;
• hammer.

Interior door handle installation height

Before inserting a lock into an interior door, you need to decide on the optimal location for placing the handle. To do this, it is enough to simulate the opening of a door, think about what height is most acceptable for each individual user. As practice shows, the right solution is to install the handle on the interior door at a distance of at least 1 meter from the floor plane. The presented footage looks optimal for both adults and children.

Cutting a hole for the handle

Having found necessary tools and having decided on the location of the structure, you can proceed directly to creating an opening for mounting the mechanism. First, you should mark the height of the future handle on the door plane and its end part. This is required to determine the exact location where the opening will be made for the double-sided structure.

In order not to make mistakes in the calculations, it is enough to take the latch mechanism, and then use a tape measure to measure the distance from its eye to the visible edge. The parameter must be marked at a pre-selected height on the door leaf. Once completed appropriate markup, you can proceed to selecting a suitable crown for drilling holes.

Having completed the openings you need the diameter on the plane and the end door leaf, here it is necessary to attach the opposite parts of the handle structure. If the thickness of the plane does not allow assembly of the product, excess wood should be removed using a chisel. Next, you need to strip the canvas on both sides until the handle fits tightly into place.

Latch installation

After completing all preliminary work it is necessary to position the latch in the prepared hole. handles on an interior door involves screwing it to the door leaf in a prepared opening using fasteners that are included with the product. It is convenient to carry out the work using a screwdriver. However, if the latter is not available, you can use a regular screwdriver.

After strengthening the locking part of the structure, a core is built into it, which is strengthened thanks to the screw, long part. To avoid problems with installing the core, you must first insert the key into it by moving the locking tongue of the mechanism to the closed position. Only then should you tighten the screw.

Installing a door handle on an interior door

Directly introducing the handle into a previously mounted structure is the most simple step the work being done. Here it is enough to insert a square-shaped rod into the corresponding opening of the locking mechanism.

The next step is to fix the handle with fasteners on one side of the door. To do this, you can use self-tapping screws or use zip ties. As soon as the first handle is successfully installed, it is necessary to perform similar operations with the other part of the structure, which will be placed on the back side of the door leaf. In this way, a connection will be established between both elements of the system.

Installation of a plate for inserting the lock tongue into the door frame

In order for the installation of the handle on the interior door to be considered complete, it is necessary to make a corresponding hole for the locking part of the locking system to fit into door frame. To prevent errors in calculations, apply toothpaste to the tongue of the mechanism along its vertical edge. When closing the door leaf and releasing the handle locking element docks with the box part. The remaining toothpaste mark will tell you where to make the hole for the tongue.

Application of the above method is optimal solution to determine the correct location of the plumb plate. Despite the primitiveness of the method, even specialists resort to it.

The resulting imprint from the protruding tongue of the door latch must be drawn with a stable outline using a pencil. Next, you should use a drill and a chisel, with which you will make a hole for the locking pawl to fit in, and then a metal plate with an opening. You will also first need to make openings for fasteners to fix the plate on the frame of the door.

After creating all the necessary holes, it is enough to attach the plate to the corresponding area. To fit tightly into the box, the metal element must be firmly screwed to the wooden surface.

Finally

So we looked at how to install a handle on an interior door. This material provides an example of how to embed simplest mechanism into a wooden plane. Now you have enough knowledge to cope with the task yourself, without resorting to outside help.

Putting a latch or a lock on a door is not that difficult. If you have a tool (nothing extra expensive or unusual is needed), you can do it in 30-40 minutes. And this is without experience. We will talk further about how to embed a lock into an interior door and how to install a latch.

Tools for inserting locks and latches

Embedding a lock into an interior door is not that difficult, but you will need the following tools for the job:

Not such an expensive and rare instrument. If you don’t have a drill and a crown, you can buy it at any construction supermarket or market. Since we will not be drilling into stone, there is no need to buy too expensive ones - ordinary crowns or wood drills.

Ready-made set for inserting locks into interior doors (on wood): feather drill, holder, crown

A few words about what is better - a crown or a feather drill. Cutting a hole in a door for a lock is easier and faster with a crown, and there are fewer chips. But working at the end with a crown is not so convenient, and the hole is larger than necessary. Drilling with a pen takes a little longer and there are more chips, but it’s easier to control the process. In general, there is no big difference, but most often, the hole in the canvas is made with a crown, and in the end - with a feather. But you can use a pen everywhere.

Another point: a standard crown has a diameter of 25 mm, and a hole of 22-23 mm is needed for the lock. The extra 2 mm can be easily covered by decorative trims, but with a very narrow door these extra millimeters can become critical.

How to embed a lock into an interior door: step-by-step photos

Before installing a lock or latch, you need to determine the height at which the handles will be located. The recommended height is 90-110 cm. A lock or latch is usually placed in this gap. But when the lock is inserted into MDF doors, you should not place the lock higher than a meter. The fact is that in budget models the wooden plank into which the lock is installed is 1 meter high. Higher up there will only be emptiness and you will have to re-drill the hole and figure out how to close the resulting hole. Once we have decided on the height, we can begin installation.

Recess for the locking part

Before embedding the lock into the interior door, mark the selected height on the door. Make this more convenient using a tape measure. We put a mark on the end, transfer it using a square or building level on both sides of the door leaf.

1. Take the lock/latch and apply it to the end of the door so that the middle of the lock falls on the drawn line. We mark the width of the metal locking part and the level at which the lining ends.
   
2. We take a 16 mm feather drill and apply it to the part of the lock that will be inserted into the door leaf. Using a marker or masking tape, or a piece of electrical tape, make a mark on the drill. This mark should be slightly further than the lock. We will use it to guide us to what depth to make the holes. This is especially important if the lock is installed against glass. Otherwise, you may drill too deep and damage the glass.

   

   We put a mark on the feather drill - this way we will control the drilling depth

3. Having installed a feather drill, we make several holes one under the other, forming a recess for the lock. The number of holes depends on the size of the lock. In some models 4-6 are enough, in others you will need 8-10.
4. The edges of the holes were uneven, and the wood had lifted in places. We take a chisel and remove the protruding wood fibers from the edges, working lightly and in depth (but don’t get too carried away).

   

5. Let's take it regular drill to 16 mm, put it in a drill. Use it to align the edges of the hole made. To do this, move it up and down, pressing lightly on one side or the other of the notch. This operation is needed to speed up the process, but the drill must be strictly controlled. If you are unsure, it is better to level the notch using a chisel and mallet.

   

6. Insert the lock into the resulting hole. It is usually a little larger, so there are no problems. If necessary, using a chisel or drill it can be increased to the desired size.
7. We set the lock to the desired position and attach it to the door leaf using two self-tapping screws (one at the top, the other at the bottom).

   

8. Using a pencil or a utility knife, trace the perimeter of the lock lining. We remove the lock, take a chisel and remove 1-2 mm of wood, MDF or veneer inside the markings made.

The depth of the recess for the locking part depends on the thickness of the decorative strip. Usually they try to make sure that the strip is flush with the end of the door, but it may protrude a little. Shoot little by little as you work—it’s easier to edit it than to try to restore what you shot.

We put the handles

To finish installing the lock on the interior door, you need to make holes for installing handles. The work is much less than what has already been done, but accuracy is required. The mistakes are not too critical, although it is better to try to avoid them.

The handles come with self-tapping screws for wooden doors and coupling bolts for installation in metal door. It is better to replace the self-tapping screws from the kit - they are usually made of soft metal. Unless you bought a branded foreign lock, in which the screws are hardened. And so, buy several good screws with a diameter of 1.5-2 mm and a length of about 1 cm.

Some models have decorative overlays. We align them using a square.

Installing the lock latch

Locks for interior doors usually have a rotating latch on one side that locks the lock, and on the other side there is only a lining with a slot. That is, you can’t just open the door from the outside—you need a special key. Installing this part of the lock takes literally a couple of minutes, but there are some nuances.

That's it, inserting the lock into the interior door is almost finished, all that remains is to check the work.

Mate insert

The counter part must be installed clearly so that the doors do not play and there are no problems with closing. Therefore, we try to mark as accurately as possible and take a sharpened pencil.

You know everything about how to fit a lock into an interior door. The description takes up a lot of space, the process itself takes 25-30 minutes if you’re doing it for the first time. It will take more time if you level the holes with a chisel rather than with a drill. But the total duration is the same more than an hour will not be.

Latch installation features

It is not very often that a full-fledged lock is installed on interior doors. More often you have to install a latch - a handle with a tongue. It is smaller in size and inserting it is much faster and easier.

Installing a latch on an interior door is even faster and easier than a lock. There is very little work. You can do it in 20 minutes. And this is completely without experience.

Very often, when changing doors between rooms, we are faced with the question - how to properly install a door handle with a lock? With the help of this article, you will be able to install a lock on your interior door quickly and, most importantly, correctly, avoiding the mistakes made by many inexperienced people. Actually it's not at all difficult process, y experienced craftsman it takes up to half an hour, but an inexperienced person in this matter can suffer for several hours.

In this article we will look at the installation of the most common lock design today. This lock consists of the following parts:

Lock Mortise Tools

For installation interior lock a minimum set of tools is required, you most likely already have some of them, but if you have to buy something in addition, you will not incur large financial costs.

1. Tape measure and pencil;
2. Screwdriver or drill;
3. Stationery knife;
4. Chisels 10 and 20 mm;
5. Spade drill or 23mm forstner drill;
6. 2 mm drill;
7. Wood crown 54 or 50 mm depending on the thickness of the door;
8. Masking tape.

This is a list of the best tools you will need. For sale special sets for inserting locks, they are relatively inexpensive, but it will be even cheaper to purchase everything separately. Often, such kits include a 22 mm feather drill; it is also suitable, but then you will have to widen the hole for the latch with a chisel.

Making holes for the handle of the lock mechanism

Like any installation process, the installation of a lock begins with markings. But before that, let’s protect the door leaf from accidental damage. To do this, we use masking tape to cover the end and plane of the door at the intended installation location of the lock, this is a distance of approximately 90 to 110 cm from the floor. Pasted masking tape It will not only protect our door from damage, but it will also make marking on it much more convenient.

First of all, mark the height of the location door handle with a lock. Most often, the handle is placed at a height of 1 m from the floor level. We measure this distance with a tape measure and put a mark on the plane of the door with a pencil.

When purchasing this type of lock, it always comes with a template for accurately marking the location of the holes. Cylinder lock mechanism different manufacturers may differ in diameter, so purchase a wood crown after purchasing the lock. If your lock kit did not include a template, you can print them from this article as pictures and use them when installing the lock.

Gently bend the template along the line of the door ledge and attach it to the door from the end. Depending on the thickness of the door leaf, use a sharp object (a self-tapping screw or the tip of a feather drill) to mark the centers of the holes according to the template from the end and on the plane of the door.

Using a screwdriver and a wood bit, drill a hole in the plane of the door.

Advice: When drilling, be careful not to drill through the entire door at once. When, while drilling, the pilot drill appears reverse side doors, stop and start drilling with a crown on the other side, this way you will definitely avoid chips on the plane of the door leaf.

The next step is to drill a hole for the lock latch. Using a previously applied mark using a template on the end of the door, using a 23 mm feather drill, we drill a through hole to the previous one.

Keep the drill strictly perpendicular to the door, otherwise in the future the latch may become oblique and jam during operation.

The next step is to insert the latch into the end hole, align it with the edge of the door and trace it with a pencil along the contour of the decorative frame. After this, we take out the latch and, using a stationery knife, make an incision along the marked line in the top layer of the door leaf. And only then, using a chisel, we select the hole for the lock latch. The depth of the opening should be slightly less than the thickness of the latch frame; later, when you tighten the latch with self-tapping screws, it will be pressed into the wood and become flush with the plane of the door.

Advice: Many beginners immediately begin to cut under the latch with a chisel; this is incorrect, since the door leaf is covered with a film that can be damaged beyond the cut line with a chisel, so cut off the film first.

After selecting the groove, insert the latch into place and first, using a 2 mm drill, drill out the holes for the self-tapping screws and tighten the latch into place. If the latch fits into the hole tightly, then use a chisel to cut off the contact points between the latch and the hole.

Let's start installing the handle. The handle is assembled according to the instructions supplied with it. When installing, pay attention to the location of the closing tongue on the handle; if there is one, it should be located inside the room.

On one of the cylinder mechanisms there is a rotating pin and holders for mounting screws. Remove the decorative rosette from the mechanism using the pin wrench from the kit and mount it in place, screw the second cylinder mechanism on the reverse side.

When tightening the screws, do not overdo it - pinched cylinder mechanisms will not work as expected.

Install all parts of the handle in place according to the attached instructions, and the work on installing the handle is completed. In fact, this is done much easier than it seems; you can watch a video in which you will clearly see the entire process of installing the lock with your own hands.

Installation of the lock mate

The last step of installation door lock The interior door will have a counter installed on the doorway.

Close the door and make two marks on the doorway based on the width of the lock latch.

Measure the distance from the corner of the door to the beginning of the latch.

You should have the same distance from the edge doorway before starting to deepen the mating part. It is necessary to maintain this distance in order to further closed door did not walk back and forth due to the air movement in the apartment and did not knock.

If the answer needs to be recessed into the door jamb, then we place it in place and outline its outer and inner circuit. If there is no need to recess, then we outline only the inner contour. It all depends on the gap between the door and the jamb.

Using a drill of a suitable diameter (you can also use a feather drill, if the hole then does not protrude beyond the answer), drill a hole for the lock tongue and fasten the answer in place, having previously drilled 2 mm holes for the screws with a drill.

Do not forget to widen the holes for the screws to a depth of 2-3 mm, since there are protruding parts in this place on the back side of the answer.

We install the striker in place by tightening it with self-tapping screws and try to close the door; if there is excess play, we eliminate it by bending the tongue on the striker.

The insertion of the lock into the interior door has been completed, all that remains is to clean up the accumulated debris and enjoy the new handles on the doors.

Lock mortise with cylinder

Very often a situation arises when you need to install a lock on a door that already has a handle. Any lock with a cylinder is suitable for this.

Such locks have rectangular shape and therefore the tapping process may seem complicated without the use of special tools. In fact, such locks are installed quite easily and with a minimum set of tools. You can place them at your discretion - above or below the already installed handle.

Lock installation sequence:

Installation of the lock mate:

• On open door we pull out the bolt (the retractable part of the lock) of the lock, that is, we close the lock with the key and, leaning it against the doorway, we mark what height we will have the counter part, focusing on the edges of the crossbars;
• Using a tape measure or square, measure the distance from the edge of the door to the middle of the lock and transfer this distance to the jamb of the doorway;
• Using a feather drill, we drill a series of holes according to the markings and then combine the resulting holes with a wood drill;
• Having previously secured the response part to the jamb, use a utility knife to cut along the contour, and then use a chisel to select the countersunk hole for the response;
• We install the counter part in place and check the functionality of the lock again.

Also, such locks often come with handles; the sequence of inserting such a lock does not change, only the operation of drilling a hole for the handle is added.

Well, that's it, the lock is cut in!

Be sure to watch the video on inserting a lock with a cylinder, perhaps in it you will notice some subtleties that you did not understand from the article.

If you have any questions, you can ask them in the comments. Good luck with the renovation!

In this material we will look at how to disassemble the knob handle, which has become unusually widespread on interior doors. We will also learn along the way how these handles are installed. Below you can find not only instructions in pictures, but also watch a video.

To install the knob handle, you need to mark and make two main holes on the door, according to the template, which is usually included with the handle with installation instructions. So, let's start installing the handle, disassembling it along the way.

Given an interior door:

We make a hole from the end of the door leaf for the latch. Hole diameter from 23 to 25 mm: It is convenient to make the hole with a so-called feather drill for wood.

Using a wood crown with a diameter of 50 mm, a through hole is made for the main fastening of the handle. The distance from the end of the blade to the center of the hole is 60 or 70 mm, depending on the latch that is included in the kit.

A template for installing a knob handle from some manufacturers can be found in the form of a stencil on inside packaging box or in the attached instructions. It is very convenient to use ready-made kits for installation, which are called “installation kits”. interior handles" It’s not scary (and often, on the contrary, it’s useful) if the holes are made with a diameter 1-2 mm larger than recommended. Two-position latch mechanism: provides the possibility of installing a knob on the door, with different widths the first beam of the door. The standard distance between the center of the knob handle and the edge of the door leaf is 60mm:

but by moving the sleeve under the square, you can set the distance to 70 mm:

The standard height for installing the handle on the door is approximately 950 mm from the floor level. Next, to install the knob handle, we partially disassemble the inner half of the handle to gain access to the holes for the mounting tension screws. To do this, we will use a special “key” from the pen kit or any suitable object, for example, a knitting needle. There is a special hole on the handle through which the door handle knob should be disassembled. In the photo shown it is round, but it may be various shapes. This hole is located at the bottom of the handle:

We press the spring-loaded latch through the hole, while simultaneously pulling out the handle of the interior knob.

We take out the handle and remove it completely:

Then you need to pry off the outer decorative flange of the handle with any sharp object. Take a closer look; as a rule, the flange has a corresponding groove for this:

Well, the knob handle is disassembled and we have access to the mounting screws

Further assembly of the knob handle occurs on the door in the reverse order.
First, install the latch in the door and secure it with two screws at the end. It will look like this:

The rectangular face plate of the latch mechanism is mounted flush with the door leaf. To do this, having marked under it, use a chisel to select the required depth at the end of the door leaf. The same applies to the knob striker, which is installed according to the markings on the door frame. The required depth is also sampled under it using a chisel.

Next, you can assemble the knob handle onto the door leaf, tightening the disassembled halves with mounting screws. During installation, the handle square and bushings for the mounting screws will pass through the previously installed latch, through its technological holes

Knob handles are universal and are not divided into left/right hand. The design provides for the installation and adjustment of a knob for any door with a thickness of at least 35mm.

If the shape of the knob handle is not symmetrical in the shape of a ball, etc., then having installed the knob on the door, using the method described above, remove the knob handle, and swap the outer and inner handles, achieving their correct location relative to the location of the door leaf( left or right side). The latch or lock mechanism, if any, is also given in correct location, and if required, we also swap the outer and outer sides.

The handle, assembled and installed on the door without distortion, should work easily in both directions and independently, under the action of the return spring, return to its original position. If this does not happen, then you need to check the evenness of the installation, and also tighten or loosen the mounting screws, ensuring they are evenly tightened and the knob handle moves smoothly.

It is difficult to imagine an interior door without such an attribute as a handle. It may seem complicated to the average person self installation handles on the interior door, but all doubts are dispelled if you approach the matter correctly and with a positive working attitude.

What types of pens are there?

In nature, there are three types of door handles:

• stationary mechanism;
• with a push mechanism;
• with a turning mechanism.

Stationary handles do not have a locking mechanism. The operating process of the door is carried out through the action of force from itself or on itself.

The push type has a lever-operated shutter that, when pressed, pushes the tongue inward, allowing the door to open. The materials for its manufacture are most often the following: ordinary steel or a stainless steel sample, brass, aluminum or silumin, which combines not only part of the aluminum, but also a zinc alloy. For lovers of comfort, the most acceptable option would be a sample made of brass. Material of this origin perfectly maintains a temperature similar to the surrounding temperature, which does not cause unpleasant and sharp sensations of cold upon contact.

Types of door handles

Representatives of the rotary type are similar to push ones, but do not have a lever. Thanks to their round shape, the lock is released by turning rather than pressing. This is where their name comes from - rotary. There are several examples of this type:

• models with conventional snap mechanisms;
• a device that incorporates a latch combined with a latch and a simple-format lock;
• A model that includes an additional locking latch.

Another sample of rotary handles is being produced, the additional attribute of which is a button designed to block the door. This is a convenient moment for privacy rooms, including the parent’s nest. The only negative nuance can be considered the inability to open the door without free hands, which cannot be said about lever types.

Differences in installation work

The most simple option A stationary sample of handles is considered for installation. This product is attached directly to the door leaf. Screws in the form of a curved bracket are used as fasteners. When choosing a material for fastening, it is necessary to take into account the massiveness of the door, since their ratio is directly proportional to each other.

Installing a handle on an interior door using a push or rotary mechanism is a little complicated, the reason for this is that to attach them it is necessary to immerse the lock part of the product in the door cavity. To do this, it is necessary to violate the overall integrity door design, which leads to an expansion of the list of tools used and the expenditure of a little more time. This is what gave them the name – mortise.

Handle installation

What is needed for the job?

Before you get started, you should definitely make sure that all the tools necessary for the job are available. This will certainly save a lot of time, effort and maintain the created working spirit.

During work you will need the following equipment:

1. Pencil;
2. Centimeter or tape measure;
3. Ruler in the form of a square;
4. Drill;
5. A set of drills, including a feather drill;
6. Chisel;
7. Screwdriver;
8. Bit;
9. Hammer.

You need to make sure everything is working properly electrical appliances, outline the scope of work, adjust the lighting to the proper level.

Place for the handle

You can insert the handle into the door yourself only when the door is completely immobilized. This can be achieved in two cases: by removing it from the hinges, and if this is impossible, you need to substitute a foreign object that can hold it at rest (for example, a stool).

Since overhead handles are very easy to install, there is no point in considering the process itself. In addition, the use of precisely mortise models. It is from their example that one should learn and gain experience.

Initially, we decide on the location of this unit. This refers to the installation height of the interior door handle. Often, its norm varies within 1 meter from the floor surface - this is the most optimal footage, suitable for both a child and an adult.

It is necessary to take into account the location of handles on adjacent doors, if any. It is also worth paying attention to the texture of the door itself, checking for the presence of fittings on the surface, or other distinctive irregularities and protrusions that may affect the location of the handle.

Having marked the height point on the door leaf, we draw horizontal line using a pencil and a charcoal ruler. We retreat 60 mm from the edge of the door, revealing the location of the central hole. Duplicate the data to the opposite area of ​​the canvas.

Next, you need to set the location for the tongue from the lock. To do this, you need to move the horizontal line to the end of the door and find the center point. After which the locking plate is applied and outlined at this point.

Making holes for the latch and handles

After carefully setting the markings, it is time to use the drill. With its help, the necessary holes will be made without much difficulty. When drilling, you should use a feather drill. It will allow you to more accurately and clearly make holes for connecting handles in the form of a square.

Important to remember! You need to buy equipment for such work after purchasing pens. This is justified by the fact that the parameters of each product are different and may not correspond to the available drills.

To work in the end part, a drill of a feather model is also used. The recess is made similar to the length of the snap mechanism.

Holes in the door for the handle

Then, having deliberately measured the thickness of the lining, we remove the excess with our own hands, using a chisel. We clean everything until the strip can fit tightly and completely into the door leaf.

Place the latch in the hole

Once the latch location is ready, you need to place the occupant there correctly. Difficulties will not arise if you adhere to a clear sequence.

The first thing to do is to place the locking latch in the groove that was originally cut. Next, we screw it in with two screws that are included with the product. This must be done from the end area.

After strengthening work has been carried out on the lock, the core part is immersed into it, which is secured thanks to the long screw part. A screw is placed in the decorative area belonging to the lock escutcheon.

There is a little trick to remember. For easy and smooth, and most importantly correct insertion of the core, you need to place a key in it, and the tongue must be directed to the bottom, to the closed position, and only then tighten the screw.

Installation work of handles

Handle technology general design, perhaps one of the simplest tasks done during the entire installation period. A square-shaped rod must be inserted into the resulting hole for the handle. The next step is to fix the handle on one of the sides of the door. A couple of methods can be used for strengthening work. The first is characterized by a method of fixation using self-tapping screws. The second one welcomes the method by which screwing is carried out in the presence of ties.

Installing door handles

When the first handle has been successfully installed, you need to do the same with the second. In this way, we will establish communication between both components.

Introduction of a sheer dog plate into the design

To properly install the dog plumb plate, you need to find and mark the middle of the hole on the frame box. At home, it is customary to use toothpaste, but another similar ingredient is also possible.

With one hand we press the handle and hold it in this state. Meanwhile, with the other hand, apply the paste to the tip of the dog along the entire vertical edge. Then you should close the door and release the handle. At this moment the dog will come into contact with the box part.

Press the door handle again and bring it into open position. Opening it, we find that the paste has left traces. This area will be the mark for embedding the plumb plate. This method is the most reliable and error-free. Even experts use it.

We outline the resulting imprint from the protruding part of the latch with a contour. Using a drill and a pen, we need to drill a hole for the dog. It is also necessary to make openings for self-tapping screws that act as a fastening system.

Finishing preparatory work, we screw the lining in the area where the screws are located. To ensure a tight and soft fit of the door leaf in the opening, the plate located on the opposite side of the latch is subjected to a pressing process.

From the above material emerges next instruction actions:

1. We determine the attachment point of the handle with the lock;
2. We measure the locking units and mark them on both sides of the door;
3. We make recesses to place the locking apparatus and the handles themselves;
4. We first install the core, and then the handles themselves;
5. We identify the location of the vertical plate and make a recess;
6. on self-tapping screws.

After carrying out such work, you will no longer have questions about how to install a handle on an interior door. Having done this once, you can easily repeat all subsequent installations with the same success.

One more point should be taken into account. Handles with an embedded lock should only be installed on doors whose material will subsequently be exposed to painting work. Good luck in your work process!
