Fast locking Europa Plus GU gearboxes are available in a 35mm backset only.
New style GU locks can be differentiated from their old-style equivalents by the shape at the top of the gearbox. Old-style locks have the top corner removed, whereas new versions feature a vertical groove to help with bolts for handles. The two gearboxes are not compatible, so a new-style gearbox will not fit on an old-style multipoint lock. Fast-locking Europa Plus gearboxes were not available in the old style locks and differ slightly to the other operation gearboxes, as the top groove is actually a separate, elongated hole and top groove.
GU multipoint lock gearboxes feature a latch and deadbolt and measure 191mm high (excluding the fixing lugs) by the backset + 16mm wide. The latch is 32mm high, the deadbolt measures 35mm high and there is 54mm from the bottom of the latch to the top of the deadbolt.
GU gearboxes are fixed to their faceplates with 3 screws. The distance from the top to the middle screw is 108mm, while the middle screw to the bottom screw is 92mm.
Always allow 2mm when measuring your backset and the faceplate is still attached to the gearbox.
