KFV Stable Door Lock Latch Deadbolt 2 Pins Key Wind Operated Multipoint Door Lock

To open both the top and bottom section, turn the cylinder or thumbturn on the bottom section first and then turn the cylinder on the top section to disengage the pins and deadbolts. The latch can then be retracted by the handle or a further turn of the cylinder to release the whole door.   

This unique stable door lock features 2 round pin bolts, one located on the top half, the other on the bottom half. It allows either the top or bottom parts of the door to be opened together or independently.

To close and lock the door, either the top part can be closed first, followed by the bottom part, or both parts can be closed together. Once closed, turn the thumbturn or euro key cylinder on the top and bottom parts. Shootbolts and deadbolts will engage on doing so and the door is fully locked.

To open the top door only, from either the inside or outside, first turn the thumbturn or cylinder key to disengage the deadbolt and shootbolrs. The latch can be retracted by the handle or cylinder to release the top door. To open both parts together, repeat these steps but unlock the cylinder on both the top and bottom parts to release the complete door.

Identifying a KFV multipoint door lock is sometimes difficult. Early models did not feature a stamp on the faceplate but, thankfully, any locks produced in the last few years do feature the KFV logo.

We’d always recommend removing the multipoint from the door to help identify it and that is even more important for KFV. Early models feature a yellow passivated faceplate and dark grey gearboxes, whereas new models have shiny silver faceplates and light grey gearboxes. The best way to identify them is to match the measurements up with out line drawings.

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 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.
