Yale Lockmaster AutoEngage gearboxes look quite different to regular Lockmaster gearboxes and measure only 201mm high. The top of the gearbox is 82mm from the spindle and the gearboxes feature a groove to accept bolt through fixings.
The AutoEngage gearbox is available in 45mm or 55mm backsets and is designed for use on timber and composite doors.
Gearboxes are attached to faceplates with 3 screws and cannot be interchanged with other lockmaster locks.
When measuring the backset, allow 2-3mm for the faceplate, so a 28mm backset gearbox will measure 25mm when not fixed to the strip.
This is the automatic locking version of the lockmaster gearbox. Suits regular and heritage locks.
