Genuine Fullex Replacement 35-92/62 Latch & Hook – Dual Spindle Lock Box Centre Case

The Genuine Fullex Replacement 35-92/62 Latch & Hook Dual Spindle Lock Box Centre Case is an original Fullex centre gearbox engineered for use within multipoint door locking systems that operate with a lift lever action. Designed to suit doors fitted with a Euro Cylinder, this lock case provides dependable security through its latch and hook locking features, delivering both compression and resistance against forced entry when engaged.

With 92/62mm (PZ) centres, this centre case is purpose built for doors requiring dual spindle operation, allowing independent control of internal and external handles which is commonly found on modern uPVC, composite and timber doors. The dual spindle design ensures compatibility with a wide range of handle configurations while maintaining smooth functionality and long-term durability.

The fixing points are precisely spaced with 108mm from the top fixing to the centre fixing and 108mm from the bottom fixing to the centre fixing, allowing for straightforward alignment when replacing an existing Fullex gearbox. The overall length of 228mm ensures it sits perfectly within the door’s multipoint strip, making it an ideal direct replacement when your original centre case has worn or failed.

As a genuine Fullex component, this lock box centre case is manufactured to exacting standards, ensuring consistent performance, reliable engagement of the hooks and latch, and compatibility with existing Fullex multipoint mechanisms. It is specifically designed to restore the original operation of your door without the need to replace the full strip, making it a cost-effective and efficient repair solution.

Regular maintenance of your multipoint lock is essential for longevity and smooth operation. We recommend periodically lubricating the gearbox and moving parts with GT85 to keep internal components working freely and to prevent stiffness or premature wear, especially on doors exposed to the elements.

Whilst upgrading your multipoint door lock, it is the perfect opportunity to enhance both security and appearance. You may wish to replace your door cylinder with a high security 3 star Euro Cylinder for increased protection against snapping and picking, or consider upgrading your door handles at the same time for a stunning visual improvement and refreshed functionality.
