GU Secury A3 Classic Latch 3 Deadbolts Multipoint Door Lock – Automatich Deadbolt & slam shut operation – Classic version

This version of the GU Secury features an additional deadbolt case and the main gearbox positioned higher up the lock at roughly the same height as a traditional timber door nightlatch.

The GU Secury A2 lock features an automatic slam-shut mechanism. The faceplate is fitted with a top and bottom actuator next to the deadbolts. As the door is closed the actuators strike the frame keep and trigger the top and bottom deadbolts. They lock into their keeps without the need to move the handle. Once the door is closed the lock is automatically activated often referred to as slam shut or automatic locking. Once the door is closed the lock can then be deadlocked by turning the key or the thumb-turn on the cylinder to throw the center deadbolt. The other deadbolts are then locked in place so that the bolts cannot be retracted without the use of a key.

This door lock has become popular in the new range of composite and timber doors in residential developments. In addition, the door remains true as it’s held by bolts at the top and bottom without relying on the owner to pull up the door handle.

We’d recommend using a pull handle and separate escutcheon rather than lever handles with this lock.

Latch Reversal Instructions

Push a flat-bladed screwdriver into the small rectangular slot above the spindle and pull out the latch at the same time. Reverse and reinsert.
