The Winkhaus Thunderbolt Pyro is a high-security multipoint lock specifically engineered for timber and composite doors, including FD30 fire-rated applications. This lever-operated system features four independent deadbolts that engage firmly into the frame, providing robust resistance against forced entry and maintaining an effective weather seal.

The unit incorporates a high-performance sprung gearbox, which has been rigorously tested to 100,000 cycles. This mechanism ensures smooth operation with low handle force while effectively preventing handle droop over time. As a split spindle lock, it is compatible with lever/pad handle configurations to provide flexible access control options for external doors.

Typically used in both new installations and as a high-security replacement part, the Thunderbolt Pyro is Secured by Design accredited and meets the requirements of PAS 24 and EN 14351-1. Its non-handed design makes it a versatile solution for a wide range of residential and commercial door sets, offering long-term reliability and peace of mind.
