Frequently Asked Questions:

How do I know if this gearbox will fit my Fullex lock?
The critical measurements are the 35mm backset and 92mm PZ (handle centres). You'll need to remove your existing gearbox to measure accurately. The lock case length of 227.5mm and screw hole spacing of 108mm are also important compatibility factors. If your measurements match these specifications exactly, this gearbox will fit.

Can I reverse the latch for different door configurations?
Yes, this gearbox features a fully reversible latch mechanism. Simply remove the screw from the end of the latch, rotate it 180°, slide it back in, and retighten the screw. This allows the same gearbox to work on both left and right-handed doors.

What tools do I need for installation?
You'll need basic tools including a screwdriver set, measuring tape, and possibly a drill for any adjustments. The installation process is straightforward for anyone with basic DIY skills, though professional installation is recommended if you're unsure about door hardware work.

Is this a genuine Fullex part or a compatible alternative?
This is a genuine Fullex XL replacement gearbox, not a generic alternative. It's manufactured to the same specifications as the original equipment and carries full PAS23/24 and Secured by Design certification, ensuring reliable performance and insurance compliance.

Will this gearbox work with my existing handles and cylinder?
Yes, this gearbox is designed to work with your existing lever/lever handles (with 8mm spindle) and euro cylinder. The 92PZ measurement ensures proper alignment with standard handle sets, while the single spindle design provides reliable lever operation.
