Mortise Locks

What is a Mortise Lock?

Typically found in wooden doors, a mortise is a lock type that is placed inside door holes and has only the rear visibility. The interior of the mortise may be a deadlock or a sash lock. These two forms of mortice utilize the latch to fasten and hold doors in place. The bolts mechanism is enhanced by sets of lever grasp or knobs placed on the door sides. The chief components of the Mortise assemblages include The Lock frame: the mortice component placed inside the door; the lock trim commonly present in the lever, and knob variances. The strike plate; the metal stripe clamped to the doorpost having a cavity for the lock to glide in as it keeps the door closed and a key to fasten and unfasten the bolts. Mortise locks arrive in 2 categories; The Lever mortise and the Cylinder Mortice Locks

The lever mortise locks are the conventional mortice locks placed in homes and domestic assets. The working mechanisms of many lever mortises are similar. The turning mechanism of the key inside the lock raises the lever to a height high enough to allow the bolt to unlatch or latch. The lever mortise lock type comes with various numbers of levers and decisions are made consequent on the thickness, diameter, depth, need, and the application to which the lock is desired. The depth of the lock is a function of the levers. More lever stacks mean more depth with high security. By implication, there is less likelihood of opening the lock with another key. For instance; a lock with five levers is more secure than two levers.
