Mortise locks are very common due to their ease of installation and high reliability. To put such a lock, you need a minimum of tools and knowledge of some of the subtleties of this work.
You will need
- - a chisel;
- - hammer;
- - a screwdriver for a cross;
- - drill and drill;
Instruction manual
1
Select a location on the door leaf to install the lock. If he will be alone on the door, position him, in height, approximately in the center. In the event that the castle is placed as the second, put it a little higher or lower than the first.
2
Putting the lock sideways to the door, outline it with a pencil - you will get the contours of the groove, which will need to be selected in the door leaf. Mark the installation location and from the end of the door. With a sharp chisel, carefully select the area under the castle bar (by its thickness). Then hollow out the groove in the end of the door - so that the lock body fully enters into it. Make a groove exactly in size, the lock should not hang in it.
3
Now mark on one side of the door a place for the lock cylinder. Drill a hole in the center of the mark, strictly perpendicular to the door leaf, with a small diameter drill. On both sides of the door, focusing on the hole, mark the contours of the groove under the cylinder. Insert a drill with a diameter of the order of a centimeter into an electric drill, expand the drilled hole with it. Then, with the side edges of the drill, like a milling cutter, select a groove.
4
Insert the lock into the groove made at the end of the door. Replace the larva: inserted into the lock, it will no longer allow it to fall out of the groove. Secure it with the long screw supplied with the lock. Now screw the mounting screws into the lock rail. To facilitate their screwing, you can pre-drill with a millimeter drill holes 2/3 of the length of the screws. Install decorative overlays on the larva from the outer and inner sides of the lock.
5
You just have to install a metal strip on the door jamb, which will include the lock bolt. It is necessary to precisely mark on the jamb the place in which, when the key is turned, the bolt abuts. You can do this in different ways - for example, anoint the end of the bolt with nail polish or any other bright paint and determine the right place from the print on the jamb. Another option: cut a piece of tape or adhesive tape and stick it with the non-sticky side on the crossbar (you can lightly grease it with honey). Close the door, turn the key - a piece of insulating tape will be glued exactly in the right place.
6
Guided by the mark, select the groove for the thickness of the bar. Screw it to the jamb with screws, then chisel out the groove under the bolt, when you turn the key, it should enter without any effort. Mortise lock installation completed.
note
When choosing a groove for the larva with the lateral edges of the drill, do not press too hard - the drill may break. Use safety glasses during operation.
