Lever Operated Latch & Hookbolt Twin Spindle Gearbox To Suit Lockmaster

The YALE Doormaster Lever Operated Latch & Hookbolt Twin Spindle Gearbox is designed to seamlessly integrate with Lockmaster systems, providing a reliable and efficient solution for door repairs and refurbishments. With a compact 35mm backset and a robust 47mm case width, this gearbox is engineered for durability and ease of use.

This updated version features a convenient round hole push-to-snib mechanism, allowing for effortless operation. When replacing a snib handle, the spindle can pass through the round hole without needing to activate the snib—simply push the latch head in for smooth functionality.

Identification
It's important to distinguish this case from the Safeware version, as they share a similar appearance. The Lockmaster case measures 228mm in height, while the Safeware case is taller at 255mm, ensuring you select the correct model for your needs.

Handing
Reversing the latch is straightforward: remove the screw, flip the latch to the opposite hand, and reattach the screw for a customized fit.

Operation
To lock, lift the lever to engage the mechanisms, then turn the cylinder fully. Unlocking is just as simple—turn the key fully and push down on the lever.
