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.
