Winkhaus 45/92 Cobra 2 Hook PVC Multipoint Lock

Description The Winkhaus 45/92 Cobra 2 Hook PVC Multipoint Lock secures uPVC, composite, and timber doors prepared for a 45mm backset multipoint centre case. The latch holds the door closed once shut, while turning the key throws the deadbolt from the centre case. In addition, lifting the handle engages the hook locking points positioned along the door edge. To properly install the lock, a 16mm faceplate runs the length of the mechanism and sits within a square end recess. The centre case carries the latch and deadbolt and aligns with the primary frame keep. Furthermore, one hook sits above the centre case and another sits below. This is to ensure that these hooks pull the door tightly into the frame when the handle is lifted. At the centre of the lock, the handle spindle passes through a single follower inside the centre gearbox. Lift lever operation then drives the hooks from the lock strip and into their frame keeps. For accurate positioning along the strip, the top hook sits 735mm above the centre case, while the bottom hook sits 755mm below the centre case. Consequently, the hook-to-hook spacing measures 1490mm, and the overall faceplate length measures 2105mm. To maintain the lock over time, routinely service the hooks making sure they enter the frame keeps without resistance. In addition, apply light lubrication to the latch and hook while avoiding heavy grease for a smooth lift lever action.
