DuraVent PolyPro Metal Wall Strap: supports vent pipe from a wall or overhead
The DuraVent PolyPro Metal Wall Strap is a metal support for vent pipe. It holds the pipe against a wall or hangs it from above, along upright runs, horizontal runs, and offsets where the vent changes direction. Its legs rotate all the way around to suit the mounting spot. It accepts standard 3/8 inch threaded rod, sold separately. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. This strap also fits concentric PolyPro. Choose a 2, 3, 4, 5, 6, or 8 inch size, then coated steel or stainless steel. The 5 and 8 inch sizes come only in coated steel.
The straps carry the vent’s weight, not the appliance. They support each horizontal or sloped section and the upright runs, with support near each elbow or tee. The vent must use DuraVent PolyPro parts rather than another brand’s pipe or joint system. Connections to PVC, other polypropylene venting, or metal venting need the appropriate DuraVent adapter.

The DuraVent PolyPro Metal Wall Strap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
