Field Controls Company 6 Inch Barometric Damper With Tee 24-ga
6 Barometric Damper - Barometric dampers stabilize flue draft by drawing room air into the flue. Why do this? Too much draft causes erratic burning and wasted fuel. A stable draft provides stable heat and efficient fuel consumption. It operates automatically. A flap swings open wider as draft increases, thereby letting in more air. And as draft reduces, the flap closes to reduce air. Our high-quality model is packed individually, each with its own tee included. Dimensions L x W x H 7 x 7 x 4.5 inches, Weight 1.8 Pounds, Weight 6.23 Pounds, Brand Name Copperfield Chimney Supply, Manufacturer Copperfield, Part 321
