Product Code: 16013. A door closer for light or medium weight internal doors. Designed to be completely concealed when the door is closed, and compact enough to be unobtrusive when the door is open. The closer comprises a small chain anchored at one end to an end plate which is screwed to the door jamb and connected at the other end to a spring contained within a steel cylinder which is fitted into the butt stile of the door. The spring is compressed when the door is opened, and its extension when the door is released acts through the chain to pull the door closed again.
