CY-03 mortice lock from the Big CY range: a three-bolt lock body that sets into the edge of a door and takes a profile cylinder. A sprung latch bolt and three square deadbolts throw from a long silver-finish forend, so the door locks at several points along its edge. The case is black, with a brass-coloured follower hub for the handle spindle and a keyhole-shaped cut-out for the cylinder. Screw holes at each end of the forend fix the lock to the door.
