CY-04-BH mortice lock from the Big CY range, with four round deadbolts, a black case and a profile cylinder cut-out, made to set into the edge of a door. The four cylindrical silver deadbolts and a sprung latch bolt throw from a long silver-finish forend, locking the door at several points along its edge. A brass-coloured follower hub takes the handle spindle, and the keyhole-shaped cut-out takes the cylinder. Screw holes at each end of the forend fix it to the door. Catalogue code: 37172
