Made of galvanized steel. The 6 inch backdraft damper prevents reverse air flow when fans are shut off with spring loaded clamp closures. Saves CO2 and prevents odors from exiting a room or enclosure. The back draft damper also includes rubber gaskets already pre-installed on the exterior for an air tight seal.
