DuraVent PolyPro Locking Band Clamp: joins pipe sections cut to length
The DuraVent PolyPro Locking Band Clamp is a band clamp that joins cut sections of vent pipe. Cutting a pipe to length removes the tab that the standard locking clamp holds onto. This band clamp makes that connection instead, and it is also useful at joints in tall vertical runs. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. Choose the size to match your vent: 2, 3, 4, 5, 6, or 8 inch.
PolyPro joints push together, with the narrower end sliding into the wider end over a rubber gasket. The ends overlap by 2 inches. Every pipe and fitting comes with a locking clamp on its wider end to secure the exhaust joint. This band clamp serves the cut sections where the usual tab is missing. Standard gray PolyPro parts belong indoors. Outdoor sections exposed to sunlight use black parts made to resist sun damage, including outdoor elbows, tees, and terminations. Joining uncut parts? See the DuraVent PolyPro Locking Clamp for uncut pipe. The DuraVent PolyPro Locking Band Clamp ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
