3 Lever Mortice Sash Locks

3 lever mortice sash locks provide a practical locking solution for doors fitted with lever handles or door knobs. Installed into the edge of a timber door, these locks combine a spring latch and a key-operated deadbolt within a single lock case. The latch allows the door to open and close using the handle, while the key-operated bolt can be engaged to lock the door when additional security or privacy is required.

A 3 lever mortice sash lock uses three internal levers that align when the correct key is inserted and turned, allowing the deadbolt to extend into the door frame. This design provides dependable everyday locking while remaining simple to operate. Because of their moderate security level, 3 lever mortice sash locks are commonly used on internal doors such as bedrooms, home offices and other areas where privacy is needed.

Suitable for both new installations and replacement mortice sash locks, these locks are manufactured from durable materials to ensure smooth operation and long-lasting performance. Available in a range of sizes and finishes to complement your door furniture, 3 lever mortice sash locks offer a convenient combination of latching and locking for internal timber doors.
