This genuine replacement gearbox is designed for use with Yale YS170 multipoint locks, featuring a 35mm backset. It acts as the central mechanism within the locking system, enabling door handles to operate the latch and hooks for secure closing and opening. The unit fits into the lock strip, typically without major adjustments, making it suitable for repair or maintenance of PVCu and composite door systems.
On site, this gearbox is commonly used to restore functionality to doors where the central drive mechanism has failed, without needing to replace the full lock. Installers can swap out a faulty gearbox by removing the multipoint lock strip, fitting the new part, and reassembling the door furniture. This helps maintain security and reliable operation of entrance and exit doors in residential or light commercial settings.
