Secury A2 Genuine Multipoint Gearbox – Automatic Locking

GU Secury A2 automatic gearboxes were fitted to one of the first automatic locking multipoints. They are available in 35mm, 45mm, and 55mm backsets.

GU multipoint lock gearboxes feature a latch and deadbolt and measure 185mm high (excluding the fixing lugs) by the backset + 18mm wide.

Always allow 2mm when measuring your backset and the faceplate is still attached to the gearbox.

We stock a range of associated products for GU Secury A2 gearboxes, including multipoint door locks, keeps, spindles, handles and accessories.
