Mortise Locks
A mortise lock is installed within a pocket, known as a mortise, that is cut into the edge of a door. Because the lock body is housed inside the door rather than mounted on its surface, mortise locks provide a clean appearance while delivering exceptional strength and reliable performance.
Designed for demanding applications, mortise locks are commonly used in offices, hospitals, schools, multifamily properties, industrial facilities, and public buildings. Their heavy-duty construction and wide range of operating functions make them an excellent choice for doors that experience frequent use.
Many models are available with ADA-compliant lever trim for accessible operation, and select functions include an integrated deadbolt for added security. Compared with standard cylindrical key-in-knob locks, mortise locks offer a broader selection of locking functions and greater design flexibility.
Built to withstand years of daily use, mortise locks provide dependable performance and an extended service life, helping reduce maintenance and replacement costs over time.
