Mortise Deadlock and Deadlatches

What are Mortise Deadlocks and Deadlatches?

Embedded directly into the door, a mortise deadlock allows for manual locking with a key or thumb turn from both sides.

Conversely, deadlatches ensure automatic locking upon closure, combining convenience with robust security. With an array of options from single to double-cylinder and diverse core types, we ensure compatibility with any security requirement.
