Mortice Locks

The term 'mortice lock' is commonly misused to determine a specific type of lock - when in fact there are many types of mortice lock, as the term itself determines that the lock is morticed into the door, rather than surface-mounted or clamped like other types of locks may be. 

The principle types of mortice locks are mortice sash-locks and mortice dead-locks.  

Sashlocks work with a set of handles and a key, so the door can be held closed on the latch and optionally locked via key, whilst deadlocks only work from a key, meaning they would not hold the door closed unless locked.

In addition to the typical mortice sashlocks and deadlocks, you will also see we have a range of more specialist locks for specific applications, including sliding door locks which offer hookbolts or claw-bolts, fire rated locks commonly used in fire doors, escape locks used on communal escape doors, mortice nightlatches which use a key to operate the latch (similar way the traditional yale latches, but morticed in rather than surface mounted), horizontal locks originally fitted into very old doors, and even mortice locks for metal doors.  You'll see all these options below.
