Keywind operation

Two full turns of the key lock the mechanism; two full turns unlock it. A further turn retracts the latch. The latch can be reversed by removing its retaining screw, turning the latch over and refitting it.

Check compatibility before ordering

Compare the photographs, case shape, fixing positions and measurements with your existing gearbox. A matching backset alone does not confirm compatibility. This is a keywind centre gearbox, not a complete multipoint locking strip.

What is included?

One gearbox only. Cylinder and fixing screws are not included.
