SureFire Classic 2 Hook Multi-Point Lock for Composite/Timber Doors 45mm Backset Round End

The centre deadbolt can be thrown using the key to deadlock. To release, simply turn the key. The unidirectional throw of hooks provides the lock with an enhanced anti-jemmy feature; and the twin tapered anti-jemmy hooks are designed for both high performance and security. The hooks have anti-saw protection and hardened anti-drill inserts and the hooks will auto deadlock once activated for anti-separation resistance giving 10mm (maximum) engagement into keep. Manufactured from lightweight aluminium used within the aerospace industry, these hooks have been designed with lighter torque (0.8-1Nm) to ensure key operation is smooth and easy to turn. Manufactured from injection moulded hardened Stainless Steel, the Latch Bolts have been designed to ensure the door is in the correct position before the hooks engage into the keeps to prevent any side load pressure on the hooks during any normal lock operation. The deadbolt throws 20mm to prevent against unauthorised entry and has a PTFE (plastic) lead to support low effort release.
