Description The Winkhaus 35/92 Cobra 2 Hook 20mm Faceplate Radius Ends Composite Multipoint Lock secures composite and timber doors prepared for a 35mm backset multipoint system. It’s the perfect replacement for centre gearbox locks that use a euro cylinder with 92mm PZ centres. The latch holds the door closed during normal use, while the deadbolt secures the centre case when the key turns. In addition, lifting the handle drives the hook locking points into their frame keeps. For correct installation within the door edge preparation, a 20mm faceplate runs the full length of the mechanism and fits into a radius end recess. The centre case carries the latch and deadbolt and aligns with the main frame keep. Furthermore, a hook sits above the centre case and another sits below, and these hooks pull the door tightly into the frame when the handle is lifted. At the centre of the mechanism, the handle passes through a single spindle follower inside the centre gearbox. The Lift lever can then drive the hooks out from the lock strip and into the frame keeps. For accurate positioning along the door edge, the top hook sits 735mm above the centre case, while the bottom hook sits 755mm below the centre case. Consequently, the hook-to-hook distance measures 1490mm, and the full faceplate length measures 1770mm. To maintain reliable performance over time, we recommend that you routinely service and check that both hooks enter the frame keeps without resistance. In addition, apply light lubrication to the latch and hook during maintenance. This will help maintain smooth engagement and reduce wear within the centre gearbox.
