Lockmaster Single Spindle Slave Gearbox 35mm
A replacement slave centre case for the Lockmaster / Milamaster door lock mechanism. This slave type door lock does not have a latch or deadbolt and is used in the secondary door on a pair of french doors. If you're having problems with your door lock, the gearbox is almost always the problem and changing it is as simple as removing a few screws.
- Important measurements: 35mm Backset / 92mm PZ Centres
- This is the mechanism inside the door that is operated by the handle.
Most likely to be the problem when a lock fails.
Double Spindle - for lever/ lever operations
