Union Martin Handle Lock
The Union 2 Lever Lock with Martin style handles provides a complete security solution for internal timber doors in residential and light commercial settings. This mortice set includes the locking mechanism, a pair of levers on backplates, and the necessary strike plate for a standard installation. It serves as a reliable choice for areas requiring basic privacy and security without the complexity of high-security cylinders.
Built for the Job
Site supervisors and carpenters specify this hardware for its standardized dimensions, which simplify the process of retrofitting or installing on new door leaves. The 2-lever mechanism offers a balance of functional longevity and ease of operation. Because the handle and lock come as a matched set, contractors avoid compatibility issues between the spindle, backplate, and keyhole alignment. The assembly withstands frequent daily use in high-traffic internal corridors and office rooms.

On-Site & Workshop Notes
-
Ensure the mortice pocket is cut precisely to the case depth to prevent the faceplate from sitting proud of the door edge.
-
Lubricate the latch bolt and deadbolt with a light silicone-based spray during commissioning for smoother mechanical action.
-
Check the spindle length before final fixing; trim if the door thickness is at the lower end of the specification to ensure the handles seat flush.
-
Avoid using aggressive chemical cleaners on the handle plates as this can degrade the protective finish over time.
