What Is A Mortise Lock?
A mortise lock is a lock that requires a mortise (a deep pocket) to be cut into the door where it will be installed. The bolt of the lock is then placed into the mortise. Because it is drilled into the door itself, it relies on the strength of the frame, and is therefore more secure than locks that are simply attached to the outside of the door frame.
Where are Mortise Locks Used?
A mortise lock is a great way to secure your door, though it’s typically used on older doors and construction. They were used less with the advent of bored cylindrical locks, but have recently enjoyed a comeback in commercial and residential construction because of the additional durability and security they offer over bored cylindrical locks. Mortise locks can endure several decades of use when properly used and maintained.
