DuraVent DuraChimney II 8 to 16 inch Supplementary Support: carries chimney weight on runs taller than 50 feet
The DuraVent DuraChimney II 8 to 16 inch Supplementary Support is a clamp that transfers chimney weight to the house framing. It wraps around the pipe and fastens to the framing with a 2 inch air space between them. The nut and bolt for tightening the clamp are included. You need this support when the chimney exceeds 50 feet, or whenever the fireplace maker requires it. One support holds up to 25 feet of chimney, so taller runs may need several. Below 50 feet, the anchor plate at the fireplace carries the load unless the fireplace maker calls for extra support.
DuraChimney II is DuraVent’s air cooled chimney, a double wall pipe in 8 to 16 inch sizes for fireplaces that burn wood, oil, coal, or gas. Choose the diameter that matches your chimney: 8, 10, 12, 14, or 16 inch. Wall straps still hold the chimney to the wall every 8 feet. Only need to keep the pipe centered inside its enclosure? See the DuraVent DuraChimney II 8 to 16 inch Stabilizer, a centering clamp that carries no weight. The DuraVent DuraChimney II 8 to 16 inch Supplementary Support ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
