GU Secury Automatic Multipoint Lock – 55/92, 6' 8" Door (6-40526-05-R-SS)

The GU Secury Automatic is a gear-driven European Profile cylinder multipoint lock designed for modern, clean-looking doors. This lock operates without lever handles – simply use your key from the exterior or thumb turn from the interior to lock and unlock the door.

What makes the Secury Automatic stand out is its automatic latching system. Every time the door closes, the top and bottom latches extend 3/4 inch (20mm) to secure the door in the locked position without any additional handle lifting. This keeps the door in proper alignment and eliminates the need for a second operation to engage the multipoints.

To open the door, turn the key or thumb turn 180 degrees to retract the deadbolt, then an additional 180 degrees to retract the latches. The lock is constructed from durable 304 stainless steel for long-lasting performance.
