CY-01-S mortice lock combining a spring latch with a single deadbolt, from the Small CY range of mortice locks. Fitted into a pocket in the door edge, the angled spring latch holds the door closed while the square deadbolt locks it into the frame. The lock case is black, with a brass-coloured splined hub that takes the handle spindle and a keyhole-shaped cut-out for a lock cylinder. The latch spring is visible inside the case. Both bolts project through a long, brushed silver-tone faceplate with fixing holes at each end. Catalogue code: 37164
