The Lockwood Paradigm® 005 Double Cylinder Deadbolt is a premium high-security deadbolt for external entry doors, using key operation from both sides for maximum security. DualSelect® gives three operating modes; turn the key once for Safety Mode (locked outside, free inside) or further for Secure Mode (locked both sides), with Passage Mode for everyday use. SafetyRelease™ automatically unlocks the inside knob on key entry from outside, reducing the risk of being locked in. LockAlert® shows the lock status at a glance from inside. The cut-resistant stainless steel bolt with counterbalance design distributes load between door and frame for added attack resistance. The square rose fits standard 54mm holes for easy retrofit, with a 60-70mm adjustable backset suiting most doors. Kinetic Defence® bump and pick resistance is built into the 5-pin brass cylinder with 78,000 key combinations. Tested to AS4145.2-2008 (SL8 security, D8 durability). Backed by Lockwood's 25-Year Mechanical Warranty.
