Lockmaster Slave Multipoint Lock Single Spindle Unsprung

The Lockmaster Slave Multipoint Lock is a full-length security mechanism designed for the secondary (passive) leaf of a pair of double or French doors. Unlike standard master locks, this slave unit is manufactured without a central latch or deadbolt, focusing instead on providing robust multi-point engagement to secure the door leaf against the frame and the adjacent active door.

Equipped with a 16mm faceplate, this unit is compatible with various PVCu and timber door systems using standard Eurogroove specifications. The gearbox is unsprung, meaning it is designed to be paired with sprung handles which provide the necessary return force for the lever. This setup ensures smooth operation and longevity of the internal components.

Typical applications involve residential French door sets where the slave lock works in tandem with the master lock to provide a comprehensive security solution. It is commonly used as a replacement part for existing door systems or as an integral component in new door fabrication, ensuring consistent locking pressure and alignment across the entire height of the door leaf.
