Mortise Handlesets

If you are looking for superior security this lock is what you’re shopping for. Mortise locks fit into a pocket custom built for your door. Some doors come pre-fabricated for these locks but for those with doors that need this pocket made, it is best to leave the task to a locksmith since it can be reasonably complex. In the end, these locks are much more secure than cylindrical or tubular locks.

How a Mortise Handleset Operates
A mortise lock offers additional security by being constructed by a number of different parts. The lock’s body itself is several inches wide and the latch, which is used to lock the door, is contained inside of the lock body. This in itself makes it quite different from a typical deadbolt cylinder. The strike box is contained in the door frame and covered by the strike plate. Lastly, the trim and handles are attached to allow operation of the handleset.

Single Cylinder Mortise Locks
An entry set which is operated by key on the exterior and a thumb-turn on the interior. A single cylinder lock is most frequently used in residential locations.

Double Cylinder Mortise Locks
An entry set which is operated by key on both the exterior and interior sides of the lock. Double cylinder locks are most frequently used on glass doors, or doors that are not far from an easily broken window or sidelight. These are often used in commercial settings but can be great for optimal security in residential areas. 

Dummy Mortise Locks
Dummy handle sets are almost always used in conjunction with a matching single or double cylinder handleset.  These are intended for use on the inactive door in a set of double doors.
