Fullex XL Passive Door Lock Gearbox – 35mm Backset, 92mm Centres
Fullex XL passive gearbox
A genuine Fullex replacement centre case for the passive (secondary) leaf of a compatible Fullex XL multipoint door lock. This lift-lever gearbox has a 35mm backset, 92mm handle-to-cylinder centres and a single 8mm square spindle follower.
This is the passive version. It is not a replacement for an active-leaf XL gearbox with its own latch and hook. Match your existing case and mechanism before ordering.

How to check the fit
Measure the backset from the front edge of the gearbox to the centre of the spindle follower. Check the 92mm centres against the points shown in the technical image. Compare the case outline, cut-outs, fixing positions and connection to the existing multipoint mechanism. Matching the brand alone does not establish compatibility.
The listing is for the centre case, not a complete multipoint locking strip, handles or cylinder. If you are unsure, send photographs of the existing gearbox and its measurements to our team before ordering.
