ABSTRACT:
A damper apparatus which includes a rigid frame mounted on an elongated rod. A sheet material flexible cover closely covers the frame. The frame, cover and elongated rod are inserted within a duct with the ends of the elongated rod protruding through the wall of the duct. The covered frame can be pivoted exteriorly of the duct by pivoting of the elongated rod to any desired position and be caused to remain in that position functioning to restrict the flow of gas through the duct. The flexible cover functions as a sound damper for mounting the sound that is created by moving of the gas through the duct.
