Wind Directional Chimney Cap - Galvanized 10 inch

10 Inch Chimney Cap Size : 10 inch The FAMCO research team has proven that the most effective draft inducing chimney caps are those that separate the wind stream as it flows over the cap and those that rotate to align with the wind direction. The WDC Wind Directional Chimney Cap does both to provide maximum drafting. In usage, the rotating hood is kept in proper position (relative to the wind) by the wind vane. Air movement past the hood creates a partial vacuum in the flue, enhancing draft efficiency and helping to prevent downdrafts. The WDC is engineered to slip over the O/D (outside diameter) of a single wall pipe and with the help of an adapter (WCASS) fit inside an insulated, double or triple wall pipe. Quality constructed in 26 gauge Galvanized Steel.
