The WINKHAUS AV3 Auto Locking Lever Operated Latch & Deadbolt has a 20mm radius faceplate and central firing mechanism and is ideal for use on timber, UPVC & aluminium doors. The two self-locking sturdy hooks ensure secure closure, complete with a weather-seal dual hook for a tighter seal. The door can only be opened when the deadbolts are fully retracted in the door sash, ensuring long-lasting durability and no slamming of the door with the hooks extended prevents scratches or damage to the door. The AV3 autoLock also has the optional capability of becoming an electronic access controlled locking system. The lock is designed to accept a 12v electronic motor which can then be controlled by means of industry standard multi option access control systems. When activated the two solid high tensile steel hooks and central latch are withdrawn thus forming the blueMatic AV2-E. The extreme versatility of the blueMatic AV2-E Electronic Locking system is achieved through its easy integration with all access control systems which subsequently leads to its suitability for many different applications.
