DuraVent PolyPro Single Wall Firestop Spacer: fits around the vent at floor and ceiling openings
The DuraVent PolyPro Single Wall Firestop Spacer is a two piece spacer for the openings where vent pipe passes through floors or ceilings. Its halves slide together around the pipe and attach to the framing with nails or screws. It goes at each floor and ceiling crossing, including the attic floor, but not at the roof deck. This spacer fits single wall pipe, not concentric PolyPro. Choose a 2, 3, 4, 5, 6, or 8 inch size to match your vent. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
PolyPro pipe pushes together over a rubber gasket, with the narrow end overlapping inside the wider end by 2 inches. A locking clamp supplied on the wider end of every pipe and fitting secures each exhaust joint. Gaskets take only soapy water, never petroleum grease. Standard gray PolyPro parts stay indoors. Parts exposed to sunlight outdoors are black and resist damage from ultraviolet light. Looking for a wall support? See the DuraVent PolyPro Metal Wall Strap. The DuraVent PolyPro Single Wall Firestop Spacer ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
