Union Strongbolt 3 Lever Mortice Sash Lock

This stainless steel variant features a 68mm case size with a 45mm backset, offering a contemporary finish that's ideal for modern door furniture and environments requiring corrosion resistance. The stainless steel forend finish provides excellent durability and a sleek, professional appearance that suits both commercial and residential properties. With its 57mm centre measurement and compact backset, this configuration is perfect for narrower door stiles or where space is at a premium.

The 45mm backset makes this lock particularly suitable for retrofit applications or doors with limited stile width, ensuring secure installation without compromising the door's structural integrity. The Union SwitchLatch technology allows for tool-free radius latch reversal, streamlining installation, whilst the anti-rattle adjustable strike enables precise on-site adjustment. Security is comprehensive with chamfered bolt design for enhanced side load resistance, anti-pick protection, and hardened steel pins that resist sawing attacks. The 14mm deadbolt offers secure positive deadlocking with dual-sided key operation.
