How to Choose the Right Backset:

When selecting a replacement gearbox, match the following:

• Backset Size: Measured from the center of the spindle/euro cylinder hole to the edge of the door faceplate.
• Spindle Type: Ensure compatibility with your handle spindle setup (single, inline split, or dual for offset handles).

Replacing the backset centre case is a cost-effective and time-saving alternative to replacing the entire door locking mechanism—just a few screws, and your door is secure again.
