DuraVent FasNSeal Support Clamp for W2: order 1 inch larger than your vent size
The DuraVent FasNSeal Support Clamp for W2 is a clamp that hangs a vent run from threaded rod. This is the single wall support clamp listed again for use with a W2 run. The W2 pipe’s outside diameter is 1 inch larger than its vent size, so the clamp needs to be 1 inch larger too. Choose from 4 to 10 inch sizes, plus 12, 14, and 16 inch sizes on this page. Match that choice to the outside of the pipe, not the vent size alone. Threaded rod is not included. DuraVent recommends a clamp every 10 feet along a vertical run.
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. That 1/2 inch air space helps shield heat and reduces the space needed between the vent and materials that can burn. In a house, DuraVent recommends W2 for routes inside walls or between floor joists. Supporting a single wall vent instead? See the DuraVent FasNSeal Support Clamp for single wall runs.
