Mortise Locks

Discover reliable mortise locks at SNTRY Supply, your go-to source for commercial door hardware and access control solutions. These heavy-duty locksets are installed into a pocket (mortise) cut into the door edge, offering superior strength, durability, and security compared to cylindrical locks, making them ideal for high-traffic, high-abuse environments such as offices, schools, hospitals, warehouses, and institutional facilities. Our selection includes both mechanical and electrified models with functions like storeroom (key retracts latchbolt, outside always locked), office/classroom (key locks/unlocks outside lever), entry (key or thumbturn locks/unlocks), and privacy (inside button locks outside), featuring fail-secure electrified options with 12V/24V operation, Request to Exit (REX) switches for integration with access control systems, adjustable backsets (typically 2-3/4"), ANSI/BHMA Grade 1 certification for extra-heavy-duty performance, and compatibility with fire-rated doors, panic bars, electric strikes, and door closers.
