Winkhaus STV Trulock 16mm Square Faceplate 2-Hook Multipoint Lock

The Winkhaus STV Trulock is a high-performance multipoint lock designed specifically for composite and timber doors. It utilises a lever-lever operation to engage the latch and deadbolt at the centre, while simultaneously deploying two hooks for additional security at the top and bottom of the door.

It is typically used as a primary locking mechanism in new installations or as a direct replacement for existing Winkhaus Trulock systems. The 16mm square faceplate makes it compatible with standard Euro-grooves found in modern timber and composite door profiles.

To ensure long-term reliability and ease of use, the lock features low friction hook thrust plates. This design reduces the effort required to operate the handle, leading to a smoother locking experience. The system is built to standard 92mm centres, allowing it to be paired with common multipoint handle sets. With its robust hook design and Secured by Design certification, this locking system provides a high level of physical security, effectively pulling the door into the frame to create a tight weather seal and resist physical attack.
