Description The Winkhaus Stv Cobra 35mm 3 Hook 16mm Faceplate Multipoint Door Lock secures uPVC, composite, and timber doors prepared for a 35mm backset multipoint system. It is used as ian ideal replacement for centre case locks that use a euro cylinder with 92mm handle 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 engages the hook locking points along the door edge. For consistent installation within the door edge, a 16mm faceplate runs the length of the mechanism and fits into a square end recess. The centre case carries the latch and deadbolt and lines up with the primary frame keep. Furthermore, hook locking points sit above and below the centre case along the strip. These hooks are there to draw the door into the frame when the handle is lifted. At the core of the lock, the handle passes through a single spindle follower inside the centre gearbox. Lift lever operation then drives the hooks from the lock strip and into the frame keeps. For correct positioning along the strip, the top hook sits 735mm above the centre case, while the bottom hook sits 755mm below the centre case. As a result, the hook-to-hook distance measures 1490mm, and the overall faceplate length measures 2105mm. To maintain smooth and reliable operation, routine servicing should include checking that each hook enters the frame keep freely. In addition, apply light lubrication to the latch and hook mechanisms during maintenance. For continued secure performance, confirm the euro cylinder fixing screw remains secure in the centre case, and check your door alignment if resistance appears when lifting the handle.
