Kodia EL-13B aluminium door lock, a narrow mortice lock in the 28x110mm size with a hook bolt. The long, slim body suits the narrow frame sections of aluminium doors. A bright silver faceplate carries the screw fixings top and bottom, and a chrome hook bolt with a ridged tip swings out from the faceplate to lock. Behind it sits a black lock case with a keyhole.
