Replacement Cast-Iron Damper Valve Plate

For old, rusty, warped, or missing damper plates we have replacement your next damper plates. It doesn't matter if the old damper has poker or rotary controls, in a matter of minutes you can easily slide out the defective plate and slide in a replacement plate. The large hole in the damper allows installation of a rotary control. The smaller hole is used to run a wire through and fasten the damper controls to the damper body
