At the time of buying interior doors you need to be prepared for the fact that the accessories may not come with them. You receive the canvas and posts from which the doors are made. And in this canvas there will not even be a hole drilled for the handle. The thing is that the product can be very different, have a unique design and size. And the handle, which will be installed in advance, may not be liked by residents. In this case, you need to install a door handle on the interior door. You can do this work yourself. You just need to buy a suitable handle and install it.

What types of pens are there? What is the difference? How to install a handle on an interior door? You will learn all this by reading our article.

Handle for interior doors

First, let's look at what such a pen actually is. We are all familiar with them, but it is unlikely that most have thought about it. design features. It is important for us that she helps open the door. However, during installation it would be nice to become familiar with its design. Here's what's included in a standard door handle:

1. Handle for opening doors (2 pcs.).
2. Decorative rings that cover the bolts and fastenings of the handle.
3. One rod or bar of metal that connects one handle to the other.
4. The socket is the body of the mechanical part of the structure, which cannot do without locks, springs and a tongue.
5. Stoppers that limit the movement of the tongue and handle.

But, in addition to the standard configuration, all handles for interior doors differ in the installation method, their shape, operating principle, material and the presence of a lock. If we talk about the installation method, there are two types door handles:

• overhead or stationary;
• mortise

Overlays are fairly simple products that just need to be attached to the door leaf. The work is simple and fast. But mortise door handles are installed in the door leaf in mortise holes. Here you will have to work hard.

As for the way door handles work, they are divided into the following types:

If we talk about the materials from which they are made, then there is plenty to choose from. Some are made of wood, others are made of metal (aluminum, brass), there are even glass, plastic and stone interior handles. The most popular are metal products coated with chrome, nickel, etc. The material guarantees wear resistance and service life of the handle.

Note! Products may be equipped with a lock or sold without it. This is selected based on the user's needs. When you have to close the doors often when necessary, it is better to choose models with a latch and install it.

Nuances before installing the handle

Have you ever wondered how high the handle is? This is very important because if placed incorrectly, it will be inconvenient for users to use. If it is high, it will be difficult to reach, and if it is low, you will bend over. In fact, there is no single standard that is used to guide the installation of handles with or without a latch. However, there are some recommendations.

During operation, it was noticed that the optimal option for placing the handle for interior doors regarding height is a distance of 1 m from the floor. But, each owner can raise or lower this value, based on his own preferences and the growth of family members. It is important to remember one more point - be guided by the height of the handles that you already have in your home. Then it will be easier to choose best option. Having all the handles at the same level will make them easier to use.

Tools for getting the job done

Before you start installing handles on the door, it is important to make sure that you have all the necessary tools for the job. They are simple and can be found in everyone’s home. Here is the list:

• chisel;
• pencil or marker, square and tape measure;
• drill;
• drill, crown;
• screwdriver

Thanks to this set of tools, the job will be much easier. It is clear that you can embed the handle fittings without a crown with a screwdriver, but this will take more time and effort. A drill bit is an attachment for a drill, thanks to which you can make a perfectly straight hole in the canvas in just a few moments.

It is more convenient to do the work when the door is removed from its hinges. It’s much more convenient to work this way. Therefore, do not rush to install it in its place immediately after purchase. When it is not possible to remove it, you need to secure it well so that the blade does not move during operation. This is how you can clearly and correctly mark and embed the lock.

Another important point- Read the instructions for the pen. We are used to resorting to it only after wrong actions. However, to avoid them, you just need to read the instructions first. It will indicate all the dimensions, thanks to which it will be possible to ideally select the diameter of the pen and crown.

Now you can review the installation instructions, which will help you complete the task quickly, easily and without errors. And for those who take on such work for the first time will be provided visual video.

What to do

Let's look at the list of steps after which the door handle will be installed in its place. The whole job consists of completing 6 steps. Here they are:

1. Applying markings to the canvas.
2. Creating a hole for the lock.
3. Lock installation.
4. Handle insert.
5. Applying markings on the loot.
6. Creating a groove in the loot.

This is how to install a handle on an interior door. In order not to miss important details, let's look at each step separately.

Stage 1 - applying markings to the door leaf

Have you already decided on the height of the handle? If not, then it's time to do it. After all, marking will be performed based on this indicator. To correctly mark, you will need a square, tape measure and pencil. With their help, you need to mark on the canvas the places for the holes for the handle. You should measure the distance from the floor and draw with a marker horizontal line. They move on from there, transferring the markings to the end of the canvas and to the opposite part.

Now you need to mark the place on the end where exactly the hole for the lock tongue will be placed. Along the same line on each side of the door, at an equal distance from the beginning (approximately 60 mm), a place is marked for installing the handle itself.

Stage 2 - creating a hole for the lock and handle

Using a drill and a hole saw, a hole is created for the handle. You will need to drill the leaf on each side, going exactly half the thickness of the door. To make the job more convenient, experienced craftsmen It is recommended to make a mark on the crown with a marker. Why can't you drill a hole on one side only? This way the crown can move to the side and the hole will be uneven. In addition, on the opposite side, the door trim may be spoiled and damaged. The drill is held strictly at an angle of 90 degrees. It is important not to allow deviations in any direction. And with a chisel after work you can remove and smooth out all the irregularities.

As for the hole for the lock, it is made with a drill and a pen required diameter The work is done carefully, because the distance between the corner of the end and the pen itself is not very large. There is an opinion that better first The first step is to make a hole for the latch, and then work on the handle. But in what sequence to carry out the process is everyone’s business.

Stage 3 - installation of the door lock

This is an easy task once the lock hole is completely ready. All that remains is to insert the lock into it. The lock pad is applied on top and traced around the edges with a pencil. Next comes the chisel. With its help, a layer of wood equal to the width of the overlay is removed using the marks. Then it can be recessed at the end of the door. To simplify the task, use chisels of different widths.

The overlay is fixed in the prepared place with screws. It is recommended to make holes for them in advance using a thin drill. It is enough to place the overlay in its place and mark the attachment points with a pencil.

Stage 4 - handle insertion

It's time to get to grips with the pen. They come with screws located on the outside. There is no need to disassemble this type of handle. You only need to stop one part in place, getting into the hole of the latch with its two guides. They have threads for bolts. After which the second half is attached and the two parts are tightened together using bolts. Tightening is carried out evenly so that the handle works without problems and the latch has a simple movement.

If the handle has hidden screws, then it will need to be disassembled. How to disassemble the door handle of an interior door? Often these handles come with instructions for assembly and disassembly, as well as keys for this. Based on it, we disassemble the structure, fasten the collapsible part with bolts and install the handle in its place. You should not use brute force; if everything is done correctly, the assembly will be easy.

Stage 5 - marking the loot

At this stage the door handle is ready. All that remains is to complete some details regarding the loot. You will need to cut a hole in it for the tongue and lock (if there is one). If you want the door to open and close easily, you will have to make high-quality markings.

To do this, you will need to close the interior door and mark the location of the tongue and lock on the front part, marking their top and bottom. The squares determine the exact middle of the lock and the markings are transferred to the end of the lock. Now you're ready for the final step.

Stage 6 - creating a groove in the loot

Based on the markings, using a drill and a pen, a hole is made for the tongue and lock. All excess is removed with a chisel. Next, the overlay is installed. But, before installing it, it is important to check the functionality of the handle for interior doors. You will have to close the door and check whether the handle tab and the lock fit. Don't be surprised if closed door there will be a little play or wobble. The thing is that the groove is not yet equipped with an overlay.

Now it's time to attach the bar. It is fixed flush so as not to interfere with the smooth movement of the door. In fact, the work is no different from fixing the lining on the reverse side. Use a chisel to remove all excess, drill holes, and fix the cover with the bolts included in the kit.

To help inexperienced people cope with the task, we have prepared a visual video that will show how to install door handles on interior doors.

Conclusion

Don't be upset when the door you bought doesn't have handles. This, on the contrary, is good, since you can choose a product that will be convenient in your case. And since there are so many options, there will be plenty to choose from. There should be no problems installing the handle on the interior door. Thanks to step-by-step instructions, it will be standing in just a few hours.

The door handle market offers consumers models for any room and for every taste. Installing a door handle is not an easy task; many people prefer to entrust it to specialists. But if available the necessary tool If you follow the instructions exactly, you can do this job yourself.

Types of door handles

Based on the installation method, the following groups of handles can be distinguished:

• Stationary handles. Their installation is very simple and will only take a few minutes. There are overhead and through ones.
• Latch handles. Depending on the type of handle, there are push and turn handles. There are models equipped with a keyhole or lock.
• Handles with lock.
• Mortise handles for sliding doors.
• Handles with magnetic lock.

Required Tools

To work you will need the following tools:

• pencil, tape measure, square;
• screwdriver and screwdriver;
• a drill, a set of feather drills and a 50 mm core bit (you can buy a set called “Kit for inserting latch handles”);
• hammer;
• bit;
• awl;
• chisels.

Calculation of installation height

Before you begin installation, you need to determine at what height it is most convenient to place the handle. According to GOST requirements, handles must be mounted at a distance of 1 m from the floor. But the average height of the members of each family is different, and sometimes it is more advisable to install it above or below the specified height, usually 80-120cm.

The most comfortable opening will be provided by a handle located at the level of a person’s waist.

Installation of door handles of various modifications

Below are step by step instructions, how to install a door handle of one type or another.

Installation of stationary handles

To install stationary handle, the only tools you need are a screwdriver and a drill. The overhead handles are simply attached to the door in the intended place with self-tapping screws. To install through models, you need to drill a hole in the door leaf and insert a threaded rod into it. After this, the handles are screwed onto it on both sides.

Latch handle installation

Before installing a rotary or push handle with a halyard tongue, you need to familiarize yourself with the structure of its mechanism. As you can see in the photo, the main details are as follows:

The installation process itself looks like this:

For those models that come with 3 additional screws for attaching the base to the door leaf, there is no need to drill big hole crown It is enough to make a hole for a “square” with a pen drill with a diameter of approximately 12 mm and holes for the tightening bolts. This design will last longer.

Installation of handle with lock

More complex issue– how to put a handle with a lock on the door? In order for the work to be neat, it is better to remove the door from its hinges.

Stages of work:

1. We outline the contours of the lock on the end of the door.
2. Using a drill with a feather drill, we drill several holes inside the contour close to each other, after which we remove the remains with a chisel, periodically applying a lock. It should fit there completely.
3. We make a recess for the face plate.
4. We drill holes for the handles; the diameter must be chosen so that the square rotates freely inside it. The drilling location must be marked exactly.
5. We prepare a hole for the keyhole and make a recess for the base, which can be either a bar or two circles.
6. We insert the lock and install the square pin.
7. Screw and fix the base and handles. We make a recess for the strike plate, recess it flush with the frame and fasten it.

Installation of handles for sliding doors

Installing a door handle sliding design The only tools required are a drill with feather and simple drills and a router with a cylinder cutter. Let's consider the procedure for installing an oblong-shaped handle. It looks like this:

For a round knob, the installation process is much simpler. You just need to make a round recess using a feather drill of the required diameter, and then everything is the same as in the case of an oblong one. If desired, you can additionally install, as well as an end grip, if the handle is equipped with them.

Mounting a handle with a magnetic lock

As for the question of how to insert a handle into a door if it is equipped with a magnetic latch, everything here is similar to inserting a handle with a lock. Difficulties arise only when installing the strike plate, because it is necessary that the lock clicks smoothly.

You need to do the following:

1. Close the door and mark the top and bottom of the magnetic latch on the frame.
2. Attach the counter strip to the marking and mark the contour of the recess for the magnet.
3. Make a recess in the center using a feather drill or router.
4. We fasten the bar with self-tapping screws and check the operation of the lock. If you need to move the bar a little, we fill the old holes with wooden chips and drill new ones.

A process such as installing door handles yourself requires patience, accuracy and strict adherence to instructions. You can see the installation process in more detail in the video.

Installing a door handle on an interior door is done with your own hands, since door blocks are not supplied with fittings. To do this, you need to select a tool to perform the required work. Each fitting comes with instructions for use. A convenient installation height for a person from the floor covering and a design diagram are indicated. If there are no instructions on installation height, one condition is necessary for door handles. A person should not open the door in a bent position (about 1 m from the floor).

Drawing with dimensions for installing door handles

Depending on the wishes of the person, only the installation of the handle of the door opening mechanism or door handles with mechanical or electromechanical lock. The industry produces various systems for locking a home or room. The peculiarity of locks is that millions of structures must be opened with different keys.

Installation work must be performed in a certain sequence:

Step-by-step instructions for installing a door handle

Tools for work:

• screwdriver (drill);
• carpenter's meter, marking pencil;
• set of wood drills, bit for drilling large diameters.

All door handles can be divided into overhead and mortise. Mortise handles can be divided into rotary designs and rotary ones with a lock. To protect the lock from unauthorized opening, it is necessary to create production capacity for the production of locks and keys of various modifications and sizes.

Scheme for mounting a door handle

They must be protected from water, frost and from opening with a master key. Many designs require certain professional skills from the master. It is impossible to install a door handle without special skills and tools. If it is a support one, then it is not connected to the opening mechanisms.
When marking, it is necessary to determine a place that will not interfere with the rotation of the key and will be at the level of the person’s hand.

Mechanism installation process door lock with a handle

Typically they are decorative decoration doors. The rotary knobs are particularly distinguished German manufacturers. The next most difficult installation is considered to be the design of a rotary handle with a lock without a key for locking the doors. Using a simple pencil and tape measure, you need to mark the location of the hole for the handle and lock.

The process of marking a door for installing a handle

Select a metal drill for metal doors and a wood drill for wooden doors according to the diameter of the turning rod. Using a drill and pen drills, drill a hole for the latch to the depth required for the latch bar to fully fit.

The next task is to accurately drill the hole for the handle. Having removed the latch, drill a signal hole with a small drill. Insert the latch and visually determine the accuracy of the hole in the door leaf and the hole in the latch.

The process of drilling holes for door handles

Once you are sure of the accuracy, make a hole to the required size. Having assembled and secured the handle in the door leaf, we make markings for the hole with a recess. Using the selection method, pre-assembling and disassembling, we bring the size of the loot to the required size. This handle should be the same size as the thickness of the door leaf.

Marking the door for the groove

When marking the installation location of the tongue, use a chisel to hollow out a groove for the strip with screws for fastening and for the latching strip in the door frame. The rotary handle is secured with screws on both sides and is secured with a cotter pin to prevent it from being pulled out.

Installation of mortise locks with handles

Mortise locks with a rotary handle and a lock at the end of the door leaf, special design Lock cylinders are produced by manufacturers of more than a million lock options. The number of such models available is sufficient for metal and wooden doors. DIY installation mortise mechanisms begins with carefully marking the mounting mechanisms on one side of the door.

Door marking diagram for installing a door lock

Use a chisel to hollow out a groove in the body door leaf according to the size of the locking system mechanism. The mechanism is installed at the level of the end of the canvas and is closed with an overlay strip.

When working you have to use chisels different sizes, periodically sharpening on sharpening machine or a block at a certain angle.

After making sure that the lock structure is completely recessed into the door leaf, we make a signal hole using a drill with a thin drill for a rotary handle, having previously removed the lock from the door.


We check the accuracy of the hole and drill the door using a crown required size on both sides of the door to the middle of the leaf for the handle. Once the lock and handle are installed, all screws must be tightened. After checking the functionality of the lock without closing the door, you can begin marking the groove for the loot.
IN door frame Opposite the lock, make a mark on the box for the latch. Having opened the door leaf, mark, arrange and secure the door with the groove.




If the groove is marked incorrectly and the lock tongue does not fit or there is a large gap, it is necessary to dismantle the groove and move the groove using a chisel. The chute pad and the lock bar should fit snugly, but without friction.

Reinstalling the handle

If necessary, unscrew the mounting screws and use a chisel to deepen seat. Or make a cardboard lining according to size and thickness.
Watch the video to see the process of installing a lock on an interior door.

Installing door handles with your own hands is quite a troublesome task, especially if a person is faced with this task for the first time. In order to avoid difficulties during the installation process, it is necessary to consider the design and basics. Depending on this, the work may be performed with some differences.

Installation technology various types door handles have their differences

Handle design

Before installing a door handle, you need to understand the design features modern models this type of fittings. Of course, great value It has specific type system, but several general defining points can still be identified.

The design of a standard handle consists of the following parts:

• lever;
• ring;
• kernel;
• socket;
• travel limiter;
• stoppers.

You should also take into account such details as the tongue and locking mechanism, the metal cover on the box, and the tightening screw. The last detail is used when installing a handle on hollow interior doors. It acts as self-tapping screws, fixing the system by tightening opposite sides. You also shouldn’t miss another important piece of the design – the latch. If this type of locking system is present, an additional turning screw must be inserted.

Push-type door handle with tongue for secure door fixation

You should not get down to business if you are not sure that you can assemble everything in the correct sequence with your own hands. Otherwise you may lose important details or completely damage the product.

Types of handles

The process of installing handles on interior doors with your own hands may differ depending on the type of mechanism used. Typically, the following types of handles are installed on interior doors:

• On the socket– they are easy to install with your own hands, since there is no need to drill a large hole; it is enough to ensure free movement of the rod. Externally it is decorated with a rosette overlay.
• Nobs- This is a rotary system that looks like a round handle with a latch or keyhole. It's pretty convenient option, especially if you install such a system on a bathroom door, but if low-quality materials are used, it quickly breaks down.
• Push– to open the door, you need to move the handle to the lower position by pressing it. This removes the halyard latch, which returns to its place immediately after releasing the handle.

The most popular types of door handles

Required Tools

Before you try to install a handle on an interior door, you need to prepare your tools. You don’t necessarily need everything, especially if you purchased the simplest fittings. In order to install handles and latches on the doors with your own hands, you will need:

• drill;
• screwdriver;
• a set of drills, including a “feather” and crowns of different diameters;
• chisel;
• hammer;
• self-tapping screws;
• square;
• pencil;
• stationery knife;
• awl;
• roulette;
• conductor.

The last tool is a template for installing handles. It will facilitate the process of marking and drilling all the necessary holes.

A screwdriver will make the job of installing a door handle much easier.

Installing a handle on an interior door

Before inserting a standard door handle into an interior door, you need to make markings. To do this, use a square and a pencil. Measure the required height from the floor. Usually this value varies between 80-100 cm. If you have a prepared conductor, everything is much simpler. Just screw it to the door from the end. The holes will subsequently align with the tongue trim. So, let's look at how to insert a handle into an interior door with your own hands:

1. Using a drill and a crown drill, drill a through hole in the canvas.
2. Using a pin drill or a smaller hole saw, drill through the end of the door.
3. Then you need to put a tongue inside with locking system and check its operation.
4. Trace the contours of the trim and remove thin layer material so that the piece of iron is installed flush. Screw the part with self-tapping screws.
5. Insert the rod inside the already installed part. Place a handle with a ring and rosette on top. If the ring rubs against the door, you need to recess it by grinding off a small layer of coating around the hole with a chisel.
6. Screw the handle with three self-tapping screws or secure with tension pins.
7. Attach a decorative trim on top. The connection in most models is adjusted with a hex key.

In order to install the metal trim on the frame, you need to mark the position of the tongue. This is convenient to do at the stage of installing this very part into the canvas. Drill or scrape out a recess of the required size in the box. Then trace the iron plate, press it flush and secure it with self-tapping screws.

Lock mortise

It's one thing to install simple fittings, but how to install a handle with a lock on an interior door? To do this, it is better to remove the fabric from the hinges in order to carefully embed the lock.

An example of a high-quality embedded door handle simple design into a new canvas

Now let's look at how to properly install a handle with a lock on a door with your own hands:

1. Mark the position of the lock on the end of the door, outline the contours of the system.
2. Using a pen, drill several holes in the marked area, and carefully gouge out the rest with a chisel, periodically checking the passage of the lock.
3. Remove a couple of millimeters of the coating to recess the iron plate.
4. In order to insert the handle, you need to drill a hole on both sides of the blade, suitable in diameter for the free passage of the axis. To mark its position, make a mark on the lock with a pencil, set it temporarily in place and transfer the mark to the door, and then measure the required depth.
5. Secure the lock with self-tapping screws.
6. Insert the axle inside and deepen the ring.
7. Install the handle, lock it in place.

Make a recess on the frame for the pin and tongue to fit into. Press the nozzle flush and secure with self-tapping screws.

If play occurs, it is necessary to file the handle axis with a grinder. Some manufacturers put special marks on it to make this easier.

Latch Installation

Another question - how to install latches on door handles? In most cases, this is no more difficult to do than inserting the handle itself. Let's look at how to quickly install a latch handle on an interior door with your own hands:

1. Drill an additional hole in the door. It should match the position of the latch mechanism.
2. Thread the axle into the lock and install the cap on top . You need to install a plug or key lock with reverse side premises. A rotary latch is attached inside.
3. Fix the position of the parts with self-tapping screws and disguise the fastening with decorative caps, if provided for by the design.
4. An additional hole is cut on the frame for the latch tongue, if there is one. If the lock operates on the principle of fixing the halyard tongue, no additional recess is required.

As you can see, installing door interior handles doing it yourself is a troublesome task, but quite accessible even for a beginner. Please note that misalignment of parts can lead to rapid breakdown of the fittings.

Most people think that installing a door handle is a very simple task and does not deserve serious attention. But when it comes to installation, these “literate” craftsmen are often lost. So that such a misunderstanding does not happen to you, let's figure out together how to install a modern door handle on a metal entrance door and a light interior door.

When installing door handles, the main thing is to understand the principle.

With the current selection, choosing a door handle can be quite difficult. The topic of choosing from photos and videos is covered in more detail, but now we are talking about editing, so we will only go through the main positions of the direction.

• Overhead handles are considered the simplest; their installation is really extremely simple; you just need to choose the right installation location and screw in a few screws. The handles themselves can be wooden, metal or plastic, but the installation technology is the same for all;

Even a person without training can install the overhead handle.

• The through-mount handle is no more difficult to install than the previous version, but you will need a drill instead of a screwdriver. Here a through hole is drilled into which a metal pin with thread is inserted and handles on both sides of the door leaf are screwed onto this pin;

• Knob handles and rotary models are considered the most complex structures. I’m glad that the device, and therefore the installation technology, are similar for all these handles, so we will focus on these designs.

The twist type door handle is the most difficult to install.

Subtleties of self-installation of different models

If you don’t go into the design features of any specific models, then installation Most similar devices are similar, but before we embed this or that handle, let's figure out where to install it.

A few words about the installation location

If we're talking about about a private house or apartment, then where the handle should be installed you have the right to decide for yourself, the main thing is that it is convenient for you and your household. But when choosing a place, experts recommend focusing on 2 things:

1. First of all, you need to measure at what height all the other handles in your house are. After all, when one handle falls out of the overall ensemble, it is very noticeable and spoils the interior;
2. If you choose a place to install all the handles in your home, then you need to focus on your arm bent at 90º at the elbow. Naturally, it is worth taking into account the height of all family members and choosing something in between.

The installation height of the door handle according to GOST is a completely different matter. The documents state that such structures are installed at a height of 1 m, plus or minus 100 mm. This information should be well remembered by office owners and business workers in administrative buildings. Otherwise, the fire inspector will have another reason to find fault.

Entrance door handle

High quality pens entrance doors from good producers they break extremely rarely, this misunderstanding mainly happens with goods from the friendly Chinese people. Fortunately, it’s easy to find a replacement in the store, average price such a kit fluctuates around 500 rubles.

Finding a suitable handle for a metal door is not difficult.

When purchasing a new set of handles, it is advisable to remove the old trim completely and take it with you to the market.

Remove the old handle from metal door not difficult. In this case, it is not necessary to completely disassemble the entire mechanism; it is enough to unscrew the 2 mounting bolts that are located on the inside.

So, the handles have been purchased, now all that remains is to insert them. The inner lining has been removed, so there is practically nothing holding the outer lining in place. If you pull the handle a little harder it will come out along with the square pivot pin and connecting pins.

When buying a handle, it is better to choose models with an internal armored lining; they cost more, but the protection against burglary is much higher.

Next, screw 2 connecting pins onto the outer part of the new set of handles. Separate armor plates may be provided on the keyhole; if they fit the holes in the new set, then decide for yourself whether to change them or not.

Now we insert the square rotary pin into the core of the handle and mount the outer trim in its place. Keep in mind – the square pivot pin should almost reach the bottom of the hole on both handles. Otherwise, there is a high probability that the handles will break again.

When everything is inserted and screwed, the gasket is installed last inside the structure. Gaskets can be rubber or plastic, so try to take rubber ones, such as in the photo below.

The outer cover with the pivot pin and studs is inserted first. Then the inner lining is combined with it and all this is fixed with a pair of bolts from the inside.

Handle with latch for interior door

Often, several types of handles can be installed on a lock embedded in an interior door. This is especially true for lightweight latches; any rotary handles generally fit there. The main thing that swivel mechanism worked with a square pin.

The technique of inserting a light latch and a solid lock into an interior door is shown in detail with photos and videos, and we will only analyze the installation of the handle.

The handle mechanism is screwed to the doors with self-tapping screws, but so that the fastening washer does not spoil the appearance, it is covered with a decorative overlay, after which the handle is installed.

In round knob pens, both the pen itself and decorative overlay are secured using a discreet internal tab. This tongue needs to be pushed down using the special key included in the kit. The tongue itself is equipped with a spring and after removing or installing the handle, it returns to its original position.

In rotary handles, the system is slightly different; after installing the handle, you need to fix it with a small screw on the side, and then screw it on or simply put a decorative cover on the latches (depending on the model).

The screw that secures the rotary handle can be either a Phillips screwdriver or a hexagon. In the latter case, the hexagon must come with the handle.

Conclusion

As you probably noticed, the installation of door handles on entrance and interior doors is generally similar. The main thing for you is to understand the principle of the three options shown in the article, and then you will understand any model.
