The Lockmaster Slave Multipoint Lock is a dedicated security solution engineered for the passive leaf of double French doors. This full-length mechanism is designed to secure the second-to-open door, providing robust locking points without the need for a central latch or deadbolt, which are typically found on the master door lock.

Functionally, this unit features a single spindle unsprung mechanism. Because the lock is unsprung, it is essential that it is paired with sprung lever handles to ensure the handle returns to the horizontal position. It is constructed with a 16mm faceplate, making it compatible with standard door preparation and euro-grooves.

Commonly used as a direct replacement for existing Lockmaster systems, this slave lock ensures that the secondary door remains firmly anchored when the master door is locked against it. It is suitable for both maintenance and new-build applications where high-security multi-point locking is required on double door sets.
