5-Point Locking system with double deadbolts

The Winkhaus security locking system ThunderBolt unites high security with extremely easy installation. Whether they are made of PVC-U, timber or aluminium, doors will all close firmly thanks to the angled shape of the twin deadbolts. 

Solid and tight sealing

The easy-to-fit Winkhaus ThunderBolt locking systems has been especially designed with increased tolerances for door installers.

With up to 50% greater fitting tolerance ranges, wide sash-to-frame clearances and dimensional deviations at the top and bottom, as well as the use of standard hook plates it enables easy installation whilst providing very high security and peace of mind.

These locking systems can be used on the left or right and, with twin deadbolts and pivoted latch, providing a clear advantage for dealers, as no double stock is required.

The two twin deadbolts are bevelled on both sides, this means that when the twin deadbolt is inserted, the door is drawn into the frame.  The locking system also uses the extensive range of standard keeps.
