Copperfield Chimney Supply 6" Diameter Barometric Damper with Tee

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.Automatic Draft Regulation: Stabilizes flue draft by drawing in room air, ensuring stable heat and efficient fuel consumptionEasy Installation: Includes a tee for simple and secure installation in your chimneyDurable Construction: Made of high-quality steel for long-lasting performanceModern Design: Finished in black to complement a variety of chimney stylesUniversal Compatibility: Suitable for both car and van chimneys
