Frequently Asked Questions:

1. How do I know if this gearbox will fit my door lock?
   The most important step is to check the backset measurement (35mm) and the PZ centre measurement (92mm) to ensure compatibility with your existing multipoint lock. Additionally, confirming that your current lock is a Mila, Coldseal, or Swift Frame model will help ensure a perfect fit.

2. What tools will I need to replace the gearbox?
   Typically, you’ll need a screwdriver to remove the screws securing the old gearbox and a tape measure to double-check fitting dimensions (please make sure your measurements match before buying your new gearbox). The replacement process is straightforward and can be done without professional help, making it a great DIY-friendly repair.

3. How do I reverse the latch for left or right-handed doors?
   This gearbox is non-handed, meaning the latch can be reversed to suit left or right-handed door installations. To do this:

   • Locate the cross-head screw on the side of the gearbox, inline with the latch.
   • Unscrew and remove the screw.
   • Pull out the latch, rotate it 180°, and reinsert it.
   • Replace the screw securely to hold the latch in place.
     This simple adjustment ensures the gearbox works with your door's existing handing.
