Function of the passage of the lock
The mortise lock needs to be installed inside a door. The door has to be 1.75 inches or 45mm in width to keep the mortise lock inside it and not break when it is installed.
It will take a lot of time for any intruder to open a door which has a mortise lock inside it. This lock system has to be fitted in the edge of the door and when the door is ajar then you will see only the faceplate. Choosing the right mortise lock can be a tough job because of the many notches and levers that it has. The best choices would be the ones with 5 or 6 lock levers at least or even with a cylinder lock being almost impossible to open doors having these locking systems.
The difference in size
Locks can have different sizes but they are also used for different needs. A rule that you have to follow is that when you replace an old mortise lock it’s indicated to take dimensions before starting to drill new holes.
System with dual locking
The advantage for a mortise lock is that it can be locked from either side of the door and this is very useful for those who need to lock doors from outside.
Locks with aesthetic form
What is great about the mortise locks is the old antique charm that they have, making them a little bit more aesthetically pleasing compared to the usual door knobs. These locks are hard to install but this makes them more effective against intruders because they are well crafted in any door they are put in.
Locks with sliding mechanism
These locks have the advantage that they always need to be operated with a key. The process is very simple, when the key is inserted the pins will line up and the bolt is released.
The function of the passage
Some mortise locks can be found without a key and all they have is a passage function which doesn’t allow them to be locked. This is useful because you can open and close them for as many times as you want. They are often used in bedrooms or bathrooms to avoid any accidental locking from the children’s side and if this happens to have easy access to these rooms.
