These Winkhaus gearboxes are supplied in 35mm, 45mm and 55mm backsets and 92mm centres. The gearboxes are held onto the strip by 2 rivets and a screw. Spare rivets can be ordered under part number 2241553.

All Winkhaus gearboxes, apart from the AV4 measure 185mm high x backset + 15mm, making them the smallest gearboxes on the market. They measure 64mm between the latch and deadbolt and 63mm from the spindle to the top of the gearbox. They also feature a groove above the spindle to aid in the fitment of handles with a screw above the lever.

Winkhaus AV2 multipoint lock gearboxes feature an alloy sprung latch and nickel-plated steel deadbolt. Most AV2 locks also feature an independent central deadbolt, but a latch-only version of the lock is also available.

AV2 gearboxes are distinctive as they are handed. Certain models have a latch reversal screw which, in theory, makes it possible to reverse the latch on an AV2 gearbox. However, the hooks on the lock cannot be reversed and many AV2 gearboxes will have the latch reversal screw blanked off, so you should choose the appropriate handed gearbox when replacing a broken lock.

Winkhaus gearboxes are attached to the faceplate with a set of rivets. These can be easily removed and replaced for gearbox swaps but makes Winkhaus relatively unique (and therefore easier to identify) in the market. Please refer to our guide and video on how to replace a Winkhaus gearbox for full details.

Please note that you may have encountered a really old Winkhaus gearbox that is attached to the faceplate with screws, with a passivated yellow finish. The sticker on the side (red = key wind and blue = lift lever) will denote the operation of the lock. These locks were handed and are no longer available.

Upon closing the door the snib below the hooks engages with the strike plate throwing the hook bolts.

The hook bolts are now deadlocked.

To further secure the door a turn of the key will throw the central deadbolt.

To unlock turn the key to withdraw the deadlock then either turn the key again to withdraw the latch and hook bolts or pull the handle down to withdraw the latch and hook bolts.
