UNION 4L67E Auto Deadlocking AVA Rimlock

The UNION 4L67E Auto Deadlocking AVA Rimlock is a high-security rim night latch designed to offer exceptional protection for inward-opening timber doors. It is particularly well-suited for glass-panelled doors, as the internal handle can be key-locked to prevent unauthorised entry in the event of a glass breakage.

This robust rimlock features a 20mm hardened steel deadbolt that automatically deadlocks upon closing, providing immediate physical security. The outer cylinder and lockcase are protected against drill attacks by hardened steel plates and pins, while the specialised 10-disc AVA cylinder mechanism is engineered to resist torque attacks, picking, and manipulation. It is operated by key from the outside and a key-lockable knob from the inside, and comes supplied with 3 keys.
