FAQs

Yes, the latch is fully reversible to accommodate any door handing. You can easily switch the orientation by removing a single screw, flipping the latch, and re-securing it, making it suitable for both left and right-handed installations.

This unit is a direct replacement specifically for Fullex XL gearboxes found on composite and timber doors. To ensure a correct fit, you should verify two main measurements:

  • Backset: Measure from the front of the faceplate to the center of the spindle (available in 35mm or 45mm).
  • Centres: Confirm the twin spindle distances are 92mm and 62mm.

The twin spindle design (92mm and 62mm) allows for versatile handle configurations. It is often used to enable a 'split spindle' function, which prevents the door from being opened from the outside without a key even if the door is only shut on the latch, providing an extra layer of security.

The gearbox features an integrated latch and hookbolt system designed for high-security performance. It is Secured by Design certified, meaning it has been tested to meet police-preferred standards for resisting forced entry on residential doors.
