Snapped a handle getting the old gearbox out?

It's common when the lock has seized. We've pre-matched the door handles that fit this gearbox's PZ (92mm) so you can replace both together.

Operation
Lift Lever

This is a genuine Fullex XL passive gearbox – the centre case fitted to the passive (slave) lock on the secondary leaf of a pair of French doors. It has no key cylinder of its own and is operated by lifting the lever, engaging the upward-throwing hook to secure the second door once the master leaf is shut.

The Fullex XL range is offered in 35mm and 45mm backsets across single, double and split spindle configurations, but every case shares the same dimensions: 227mm high by the backset plus 15mm. This version is the 35mm backset case, giving an overall width of 50mm. The hook is manufactured from Dacromet-coated A3 sintered steel and stands approximately 23mm high for a strong, corrosion-resistant engagement.

Each case fixes to its locking strip with three equidistant screws – the centre screw sitting 108mm from both the top and bottom screws. A snib on the faceplate lets you hold the latch back during fitting and door alignment. Being genuine Fullex, fit, throw and screw centres match the original mechanism exactly.

Buying the right gearbox: This is the passive (slave) gearbox for the secondary leaf – no key cylinder, operated by lifting the lever. If your second door is operated by a key, you need the active (master) version instead.

Frequently Asked Questions

Q: What is a passive (slave) gearbox and how is it different from the active one?
The passive gearbox sits on the secondary (inactive) leaf of a pair of French doors. It has no key cylinder and is locked by lifting the lever, which throws the hook upward. The active (master) gearbox is on the keyed leaf you use day to day. If your second door is operated by a key, you need the active version, not this one.
Q: How do I check this is the right backset for my door?
The backset is the distance from the front edge of the faceplate to the centre of the spindle / cylinder hole. This case is 35mm backset. Fullex XL is also made in 45mm backset; all other dimensions are identical, so only the backset and overall width (backset + 15mm) change.
Q: Is this a genuine Fullex part?
Yes. This is a genuine Fullex XL gearbox, so the hook throw, screw centres and case dimensions match the original mechanism exactly. Copies can vary slightly and may not align with your existing strip.
Q: Does this come with the full locking strip?
No. This is the centre gearbox / case only, supplied singly. We stock a range of associated Fullex XL parts including multipoint locks, keeps, spindles, handles and accessories – please contact us if you need a matching item.
Q: What spindle does it use?
A solid 8mm spindle. The faceplate also features a snib that holds the latch back to make alignment and fitting easier.
