Check the fit before ordering
Measure backset from the front edge of the fitted faceplate to the handle-spindle centreline. Measure PZ from the handle-spindle centre to the centre of the round cylinder opening.
Compare the case shape, spindle arrangement, fixing holes and drive connections. A matching brand or backset alone does not confirm compatibility.
Test the mechanism with the door open before closing it. Do not force a binding handle.
What is included?
One replacement centre gearbox. Cylinder, keys and handle spindle are not included. The complete multipoint locking mechanism and handles are not included.
