Details

This model is a non-flanged horizontal mount exhaust backdraft damper. The blades have a felt seal on the leading edge for better protection from the weather, and are spring assisted to allow blades to open quickly. Ideal for use in roof curbs, duct work, or wall collars when using a fan or power roof ventilator. Recommended for horizontal mount exhaust applications but it is also available for vertical mount.
