DuraVent PolyPro Concentric Support Elbow: steadies the vent where it turns toward the roof
The DuraVent PolyPro Concentric Support Elbow is a 90 degree elbow that supports the vent where it turns upward. It sits at the base of the run leading through the roof and helps steady the vertical termination, the part that ends the vent above the roof. This is a support elbow, not the roof termination itself. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
Choose the size that matches your vent: 2 by 4 inch, 3 by 5 inch, or 4 by 6 inch. The first number is the exhaust pipe size, and the second is the outer pipe size. DuraVent favors a straight route up through the roof when possible. The appliance maker sets the allowed vent length and number of elbows, so those limits guide the layout. Need the part above the roof? See the DuraVent PolyPro Concentric Vertical Termination roof outlet. The DuraVent PolyPro Concentric Support Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
