Identifying a Fuhr multipoint lock is easier once removed from the door. The gearbox has a distinct triangular top above the top fixing screw and often has “Fuhr” stamped on the faceplate. While visually similar, there are subtle differences between the Fuhr 856 (lift lever), Fuhr 859 (split spindle), and Fuhr 855 (key wind) gearboxes.
