FAQs
What does '20mm Backset' mean?
The backset is the measurement from the edge of the gearbox (or lock body) to the center of the spindle hole. A 20mm backset is a specific dimension required for certain window lock designs.
How do I know if this is the right gearbox for my window?
You need to confirm that your existing window lock has a 20mm backset and look for the '05060' stamp on the teeth connector plates of the original gearbox.
Can I use this gearbox on wooden or aluminum windows?
This gearbox is specifically designed for UPVC windows. Its dimensions and fitting might not be suitable for other window materials.
Does this come with a spindle or handles?
No, this product is the gearbox only. You will need to reuse your existing spindle and handles if they are compatible, or purchase them separately.
How do I identify the 'teeth connector plates' mentioned?
These are the plates where the spindle connects to drive the gearbox mechanism. The model number '05060' should be visible on these parts.
What is the deadbolt height?
The deadbolt height is a measurement related to the part of the gearbox that interacts with the locking mechanism's bolt or latch. For this gearbox, it's 11.5mm.
Troubleshooting
Window handle is stiff or won't turn.
Check if the gearbox is correctly aligned and the spindle is fully inserted. Ensure no obstructions are present within the lock mechanism. Lubricate the gearbox with graphite powder.
Locking mechanism does not engage or retract.
Verify that the correct gearbox model (05060 with 20mm backset) has been installed. Check that the gearbox is properly secured and the spindle is driving it correctly. Inspect the locking strip for any damage or misalignment.
Gearbox makes grinding noises.
This may indicate internal wear or damage. Ensure the gearbox is the correct type and that it is properly lubricated. If the noise persists, the gearbox may need replacement.

Setup, Compatibility & Care
Setup: This gearbox is typically installed as part of a larger window lock mechanism. Ensure the window is in a secure, closed position before beginning. Remove the existing window handle and then the spindle. Unscrew the existing gearbox from the lock strip. Align the new '05060' gearbox with the spindle and screw holes, ensuring the spindle fits correctly into the gearbox. Re-attach the window handle and spindle, testing the operation smoothly before fully securing.
Compatibility: Crucially, verify that your existing window lock has a 20mm backset. The '05060' stamp on the teeth connector plates should also match your original part. This gearbox is designed specifically for UPVC windows and certain Saracen locking systems. It is not a universal part and may not fit other brands or backset measurements.
Care: Keep the gearbox clean by wiping it with a dry or slightly damp cloth. Avoid using abrasive cleaners or solvents, which can damage the internal mechanisms. Periodically, lubrication with a suitable graphite-based lubricant can help maintain smooth operation, especially if the lock feels stiff.
