Product Details

GU Secury 3-Point Automatic Lock – 45/92, 6' 8" Door (6-35856-01-R-SS)

This GU Ferco Secury 3-point automatic multipoint lock provides enhanced security and convenience for 6 foot 8 inch doors. The lock features automatic latching technology—simply close the door and the latchbolts instantly engage at 20mm projection, securing against forced entry.

When you turn the key or thumb-turn, the deadbolt engages and locks the top and bottom latchbolts, converting the system into a 3-deadbolt configuration. This heavy-duty mortise construction includes a reinforced lever return spring system for long-lasting performance.

The lock operates with an American cylinder (using a flat tailpiece) positioned above the lever, requiring just a 90-degree turn of the key to lock. The handle height is adjustable, with 36 inches recommended for standard installations. The non-handed design allows the latch to be easily reversed for left or right-hand doors.
