DuraVent PolyPro Support Clamp for the Commercial Vertical Termination: holds the roof outlet in place on the flashing
The DuraVent PolyPro Support Clamp for the Commercial Vertical Termination is a clamp that supports the vent outlet above the roof. It sits in a notch in the variable pitch roof flashing, the cover around the roof opening. The storm collar covers the clamp. Choose 5, 6, or 8 inch to match your vent size. The clamp itself is one size larger so it can wrap around the outlet’s black metal outer pipe. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
The appliance must not bear the vent’s weight. Wall straps support horizontal, sloped, and vertical sections, including near elbows and tees. Firestops, barriers that limit fire spread around openings, go at each floor and ceiling crossing, including the attic floor but not the roof deck. Fire rated walls and floors need approved firestopping wherever plastic vent passes through. The vent uses DuraVent PolyPro parts and connections only. Connections to PVC, another brand’s polypropylene vent, or metal vent need the appropriate DuraVent adapter. Need the cover above this clamp?

The DuraVent PolyPro Support Clamp for the Commercial Vertical Termination ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
