DuraVent FasNSeal W2 Vent Length with Support Plate: support for a vertical or horizontal vent run
The DuraVent FasNSeal W2 Vent Length with Support Plate is a double wall vent pipe section with a square plate around it. The plate supports the weight of a vertical run from the bottom or helps brace a horizontal run. The 3 inch size can carry up to 100 feet of W2 pipe above it. Larger sizes have lower weight limits. FasNSeal W2 is DuraVent’s double wall stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, with an air space between its two walls.
Choose a 3 to 16 inch size on this page to match the vent run. That size measures the inside opening, not the outer wall. The stainless steel outer wall and the air space help shield nearby framing from heat. W2 is used for home vent runs inside walls or between floor joists, as well as in commercial buildings. An experienced professional fits the complete run using FasNSeal parts. Need single wall support? See the DuraVent FasNSeal Vent Length with Support Plate, the single wall version. The DuraVent FasNSeal W2 Vent Length with Support Plate ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
