3" PolyPro Locking Clamp

DuraVent PolyPro is a polypropylene vent pipe system for use with water heaters, condensing boilers, and warm air furnaces. Easier and faster to install than PVC, PolyPro is engineered to save time and money. It is designed to work with existing B Vent systems by using them as a chase, making it the perfect choice for retrofitting older systems. This is used to secure two sections of uncut pipe together. Required to ensure installation complies with ULC S636. PolyPro is a 2.2 mm thick, polypropylene vent pipe for use with ANSI Category II and IV gas-burning appliances, including high efficiency water heaters, condensing boilers and warm air furnaces.
