ABSTRACT:
A mounting bracket for securing a damper in an opening formed in a wall includes four generally L-shaped segments surrounding the damper sleeve. Each segment has a generally planar wall-engaging plate and a generally planar sleeve-engaging plate. The wall-engaging plate and the sleeve-engaging plate form the L-shape of the segment. Each segment also includes a land extending generally perpendicular to the wall-engaging plate. Two of the segments are end segments and the other two of the segments are intermediate segments. The land of each end segment is connected to the land of its adjacent intermediate segment and the lands of the intermediate segments are connected together. The segments can be removed from and replaced around the damper sleeve by bending of the land connections between the segments.
