ABSTRACT:
A damper construction is provided by a sheet metal plate having fixed guide members extending therefrom for sliding movement upon a pair of parallel guide tracks on each side of the plate. The tracks extend horizontally on each side of the flue opening and slope downwardly toward the upper edge of the open front of the fireplace. The plate is movable between positions fully covering and uncovering the flue opening when the guide members are disposed in the horizontal and downwardly sloping portions, respectively, of the tracks. A handle is attached at one end to the center of the front edge of the plate for limited pivotal movement about two perpendicular axes to allow access to the other end of the handle in either position of the plate, and to allow movement of the handle to a position out of the frontal fireplace opening when the plate is in the uncovering position.
