The AVANTIS Latch & Deadbolt Twin Spindle Gearbox is a high-performance replacement centre case designed for multipoint locking systems commonly found on UPVC and composite doors. This gearbox features a unique dual-centre configuration (92mm and 62mm) with a twin spindle setup, offering flexibility for various handle sets. It provides a practical and cost-effective solution for installers, allowing for the repair of a door lock without needing to replace the entire full-length locking strip.

For security and peace of mind, this gearbox is PAS24 accredited and complies with BS6375 standards. It is built for longevity, featuring a possible service life of 50,000 cycles and high-grade corrosion resistance (EN1670 Grade 4), making it suitable for challenging environments. The unit is easily identified by its distinctive ribbed deadbolt positioned above the lever handle and its cross-pattern spindle follower.

FAQs

To ensure compatibility, you should measure the 'backset'—the distance from the front of the faceplate to the centre of the spindle hole. This Avantis gearbox is typically available in 35mm or 45mm backset options. Additionally, verify that your current lock case height is 220mm and that it utilizes 92mm or 62mm centres.

Yes, the latch is fully reversible to suit any door orientation. To change the handing, you simply remove the small screw on the latch, pull the latch out, flip it over, and then refit and secure it.

The twin spindle configuration provides two separate followers at 92mm and 62mm centres. This allows for greater flexibility with door furniture, enabling the use of different handle sets and supporting 'split spindle' functionality, which can restrict external entry without a key.

Not necessarily. If the failure is located within the central locking mechanism, this Avantis centre case serves as a cost-effective replacement. It allows you to repair the lock by swapping out only the failed gearbox rather than purchasing and installing a complete full-length locking strip.
