Description The Winkhaus Stv-Thunderbolt 45mm 5 Deadbolt 20mm Radius End Faceplate Multipoint Door Lock secures both composite and timber doors prepared for a 45mm backset multipoint system. It replaces centre case locks that use a euro cylinder with 92mm PZ centres. The latch holds the door shut during daily use, while turning the key throws the centre deadbolt. In addition, once the handle is lifted, the remaining deadbolts positioned along the strip. drive outward to secure the door into the frame keeps. For correct installation, a 20mm faceplate runs the length of the lock and sits flush in a radius end recess. The centre case contains the latch and deadbolt and aligns with the primary frame keep. Additional deadbolts are positioned above and below the centre case, so when the handle is raised these locking points extend outward to engage their frame keeps. The handles also operate the mechanism through a single spindle follower inside the centre gearbox. Lift lever action drives the deadbolts outward from the lock strip, and each bolt enters a matching frame keep as the handle lifts. For installation reference, the top deadbolt sits 735mm above the centre case, while the bottom deadbolt sits 755mm below it. To maintain the lock, we recommend checking that each deadbolt enters its frame keep without obstruction. In addition, apply light lubrication to the latch and deadbolt and avoid using heavy grease. To ensure continuous performance, confirm that the euro cylinder retaining screw remains tight within the centre case and check door alignment if handle lift becomes stiff.
