Mortice Sash Locks

Mortice Sash Locks – Secure Locking for Doors with Handles

Mortice sash locks are a popular locking solution designed for doors fitted with lever handles or door knobs. Installed within the edge of the door, these locks combine a spring latch and a deadbolt in a single mechanism. The latch allows the door to close securely when the handle is released, while the deadbolt can be operated with a key to lock the door firmly in place, making mortice sash locks ideal for both internal and external doors.

A mortice sash door lock works by retracting the latch when the handle is turned, allowing the door to open smoothly. When the key is turned, the internal deadbolt extends into the door frame, providing additional security and preventing the door from being opened without the key. This combination of latch and bolt offers a practical balance between everyday convenience and dependable locking performance.

Suitable for timber doors in both residential and commercial settings, mortice sash locks for doors are available in different security levels, including 3 lever and 5 lever versions. Manufactured from durable materials and designed for long-lasting performance, they provide a reliable solution for new installations and replacement projects. Combining strength, practicality and smooth operation, mortice sash locks remain a widely used choice for secure door hardware.
