Compatible Gu Ferco Replacement 45/92 Latch & Deadbolt – Single Spindle Lock Box Centre Case

The Compatible GU Ferco Replacement 45/92 Latch & Deadbolt Single Spindle Lock Box Centre Case is purpose built to restore the performance of older style multipoint door locks that rely on dependable lift lever operation. Designed to suit euro cylinder configurations, this centre case features a precise 45mm backset and a 92mm (PZ) centre, ensuring it aligns correctly with existing door furniture and keeps the mechanism operating as originally intended. The single spindle design allows straightforward compatibility with standard lever handle sets, while the latch and deadbolt locking features provide the familiar security and closing action expected from GU Ferco style mechanisms.

With precise fixing measurements of 105mm from top fixing to bottom fixing and 77mm from bottom fixing to centre fixing, along with an overall case length of 207mm, this replacement lock box is engineered to slot directly into many GU Ferco multipoint strips without the need to replace the full mechanism, making it a cost-effective and efficient repair solution. It is particularly suited for doors where the gearbox has worn internally but the outer strip and hooks remain serviceable, allowing you to restore smooth operation without unnecessary expense.

During installation, it is an ideal time to consider upgrading other key components of your door. Whilst upgrading your multipoint door lock, it is the perfect opportunity to replace your cylinder with a high security 3 star euro cylinder for enhanced protection against snapping and forced entry. It is also worth refreshing your door handles at the same time, not only to ensure perfect spindle alignment with this single spindle centre case but to dramatically improve the overall appearance of your door.

To keep your new centre case working smoothly over time, regular maintenance is recommended. Applying a light lubricant such as GT85 into the gearbox and moving parts periodically will help prevent stiffness, reduce wear and extend the life of the mechanism, especially on frequently used doors.
