KFV multipoint door lock gearboxes are single spindle and 92mm centres.
The overall height of the gearbox is 210mm, the bolt throws 21mm and the distance from the bottom of the latch to the top of the deadbolt is 56mm. The distance from the spindle to the top of the case is 85mm but the gearbox has both a hole and a groove to accept bolt-through handle fixings.
Older KFV gearboxes are connected to the faceplate strip with 1/8″ rivets. There are very few other gearboxes which are fitted in this way (Winkhaus being another example) which can help with identification. However, new KFV locks have gearboxes screwed to the faceplate.
KFV locks are available as either a lift lever or key wind variants. It’s worth noting that it is not possible to swap a lift lever lock to a key wind gearbox or visa versa.
When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.
Early KFV models had different rivet spacing and used different connectors when attaching the gearbox to the strip. That’s not a problem when replacing the whole lock, but worth considering if only the gearbox needs replacing as the new gearbox will not replace very early models. Brand new locks have a gearbox that is attached to the faceplate with screws.

Operation: Lift Lever
Latch reversal: Depending on the date of manufacture either:
- Push in the latch and undo the screw in the back of the lock case, remove the latch, reverse and reinsert.
- Push in the latch and undo the screw in the side of the lock case to remove the latch, reverse and reinsert.
- Pull down the serrated button to rear of the case and at the same time pull out and reverse the latch, sometimes the serrated buttons are held in place by a tiny travel pin so the serrated button will need to be pushed down hard with a screwdriver to break the pin.
