Mortise lock

Common card · No. 301378

A mortise lock (also spelled mortice lock in British English) is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. Mortise lock describes only a method of fitting the lock, and says nothing about the quality or key mechanism. In some parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. The design is widely used in properties of all ages across Europe.
