The Lockwood 303 Deadlock is a security single cylinder rim deadlock for domestic and commercial entry doors, opened by key from outside and by turn knob from inside. The lockable turn knob has an inbuilt clutching device, and positive deadlocking action secures the door when it is locked. A thick-walled, high purity zinc alloy case interlocks with the mounting plate for concealed fixing.
The 5-pin brass cylinder is individually keyed with 78,000 key combinations and features Kinetic Defence bump and pick resistance. It is retrofittable, though a strike conversion plate is required when replacing an existing flange strike.
Backed by Lockwood, an Australian brand with over 90 years of locksmithing experience.
