Copy Multipoint Gearbox – Lift Lever or Double Spindle

Avocet gearboxes are unique. They measure 218mm high x backset + 15mm. It’s the large cut-out in the top corner, that extends to below the latch, that makes them stand out. This cut-out assists with the fitment of handles where the screws are above the lever.

Avocet gearboxes feature a latch that is 29mm high, a deadbolt that is 34mm high, and 82mm between the top of the deadbolt and the bottom of the latch.

These gearboxes are not attached to the strip using conventional screws or rivets. Instead, the gearboxes are held on by arms that connect using circlips. While it is possible to remove a gearbox from a full Avocet lock, we’d advise replacing the full unit. It’s worth noting that the design of the arms has changed over time, and old gearboxes have a flat clip. New versions have a slightly curved connecting arm, that is located lower down, making gearbox swaps with new for old impossible. Please note this will only replace the latest version of this case.

When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.
