Roto Multipoint Doorlock 35mm backset 4 cam

Roto manufacture many multipoint doorlocks for the UPVC door and window market. This lock is difficult to source but we have current stock for the forseeable future. With a backset of 35mm (distance from the lock faceplate to the centre of the cylinder hole) and 92mm centres (distance between the square spindle hole and the centre of the cylinder) The 4 locking cams are different from the norm. Looking at them they appear to be flattned to a T shape.instead of round rollers found on most multipoint locks. Photo to be added soon
