The most common type of lock for doors between rooms is a latch handle. Regardless of the design and shape of the product, installation is very easy. Consider the procedure for installing such a handle on an interior door with your own hands.
Latch handle design
The models of this plan consist of two main elements: the product itself and the working mechanism. Both parts of the handle cut into the door leaf separately.
Latch models are available with or without a latch. The lock is an additional rotary mechanism. If it is not there, the door cannot be locked from the inside with a lamb, as well as with a key (a keyhole is placed on one side, and a latch tongue on the other, as in the photo).
Door handles differ in design type, but this does not affect the installation process.
Height and distance from the edge of the door
The internal element (latch) is uniform, so it is installed in the same way for different handles with a snap mechanism. The height from the bottom of the door and the distance from the edge are standard.
For latch handles, there are two options for inserting into the canvas: 60 or 70 millimeters from the edge. The rotary latch mechanism can "walk" to the right or left by about 1 cm, and this must also be taken into account.
- If the handle has a spherical shape, and the distance from the edge of the door to the decorative element of the leaf (for example, glazing) exceeds 140 mm, it is better to fix the mechanism 70 mm from the edge. If you install the handle at a distance of 60 mm, when closing the interior door from the inside, you can hit your hand on the door frame.
- When mounting the pressure product, the indentation must definitely be 60 mm.
The standard handle installation height (distance from the floor to the center of the latch) is 900–1100 mm. If the door is usually used by one person, the optimal height will be at the level of his belt.
Installation of the product on the interior door is carried out on the right or left side. For models with a round handle, you only need to turn the latch design over. At the same time, the tongue should look towards the closing of the interior door. If the device is not symmetrical, the elements simply need to be swapped, focusing on the opening side.
What will we need?
To make the embedding process as easy as possible, prepare the following: tools:
- drill (or screwdriver);
- wood crown (half a centimeter in diameter);
- drill (about 24 mm);
- chisel;
- hammer;
- pencil.
Mounting process
Step-by-step instructions for installing a latch include several steps.
markup
The procedure begins with marking the door leaf.
- Mark the spot for drilling with a pencil. Schemes are usually attached to the product.
- If there are no explanations, you can apply the dimensions yourself. To do this, mark with a pencil a distance of 60 mm from the door edge, the location height is from 90 to 1100 mm.
- We mark the central point for drilling on the side edge of the door leaf. Dimensions are applied along the center line.
Hole preparation
At this stage, we do the following:
- Using a chisel, we hollow out a recess of 3 mm under the front plate of the latch, corresponding to its width. It is better to mark the center in advance with an awl so that you do not have to re-mark.
- Using a half-centimeter crown, we drill a through hole. This is best done on both sides of the door leaf so as not to damage the door coating at the exit of the crown.
- Now let's move on to the side edge. We take a drill for wood (about 24 mm in diameter). They need to make a hole for the latch in the marked center. Do not go too deep, otherwise you can make a hole in the canvas right through to the very panel.
Product installation
At this stage, we have two holes ready.We proceed in the following order:
- We install a snap-in mechanism in the side hole, fasten it with self-tapping screws.
- Remove the top of the handle. There must be a side hole for this.
- Using the key included in the set (you can take any other thin flat object), press the tongue inside the hole and remove the handle itself.
- We remove the decorative trim, we find the mounting holes under it.
- We install the outer part of the product, and then the inner half.
- We tighten both parts with the screws that are included in the kit.
- We put on a decorative overlay and the body of the latch handle. In this case, it is necessary to press on the inner tongue with a key or other suitable object.
- Now the door needs to be closed in order to circle the place where the latch tongue touches the door frame. According to this markup, we hollow out a recess for the entrance of the lock.
- We install a decorative plastic pocket covering the wooden groove.
- We fasten a metal plate over the hole for the tongue of the latch. At this point, the installation of the handle is completed.
In the absence of a drill, all holes can be cut with a chisel. At the same time, the process of installing a door handle will require some experience and skill and will take more time.
