KFV Latch Deadbolt 2 Hooks 2 Pin Bolts Key Wind Operated Multipoint Door Lock

KFV locks have changed over time, with a significant number of locks now discontinued. New KFV locks have been designed to be modular, without the need to change routing positions for fabricators. That means that when replacing old locks, keeps may need to be moved, or hook boxes repositioned. If there is limited clearance on the original routing, this may require a small amount of work to the door to enable the locks to fit.

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. This is 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.

KFV Multipoint locks feature a couple of different hook locking arrangements.

The first is a standard hook which normally throw upwards, regardless of whether the hook is at the top or the bottom of the door.

The second type of hook is a hook and anti lift pin, which is higher security. Anti lift pins provide additional protection against attack and also require special keeps because of the proximity of the pin and the hook bolt.

The case on a KFV hook is normally 130mm high and the cases are the same size regardless of whether there is a hook, deadbolt or pin.

KFV pins are made from hardened steel to protect against sawing. Their pins are small, round bolts with a chamfered tip, which extend when the lock is thrown. Pins share common deadbolt keeps.

KFV deadbolts feature a distinctive chamfered centre which help the lock connect into the keep. The shape is distinctive, with raised parts at the top and bottom of the deadbolt which can help with identification of the lock.
