The most popular type of door lock is perhaps the mortise lock, so named because it literally cuts into the door leaf. It can be embedded, at the request of the customer, so that the lock bar at the end of the door is visible, or so that it becomes almost invisible. But this is done only by specialists, because this is a complex process that requires certain knowledge.
Such a lock is especially suitable for metal doors, as there is a door itself
the canvas protects it from breaking.
Mortise locks are divided into four classes, depending on the reliability. For interior doors, as a rule, locks of the first two classes are chosen, and for entrance doors - only the third and fourth. It is these classes that meet all the requirements for reliability and secrecy.
The most common mortise locks due to their reliability are lever and cylinder locks.
Features of lever and cylinder locks
Level-type mortise lock appeared quite a long time ago. It consists of several levers - plates that line up in one way or another under the influence of a key. The quality of the castle directly depends on how many levers are in it. To be reliable, they mustbe six or more.
But such a lock turns out a through hole that easily clogs, and if the key is lost, the entire system will have to be completely changed.
Another type of mortise lock is a cylinder mortise lock. His secret is hidden in the top hat or, in other words, in the "larva". This is a combination of the heights of the needles - small elements, which are also called pins. The largest number of these pins makes the cylinder lock especially reliable. So, for example, cylinder locks of high secrecy cannot be opened even with a vibrating master key. They are made in Switzerland and Israel.
For greater security of your premises, experts recommend installing both lever and cylinder locks on the front door at the same time.
