DuraVent PolyPro Bird Guard Screen: keeps birds and rodents out of the vent opening
The DuraVent PolyPro Bird Guard Screen is a stainless steel screen for the open end of a vent outside. It keeps birds and rodents from getting into that opening. The spring loaded screen fits inside the wide receiving end of the last pipe or elbow, called the female end. It takes the place of the rubber gasket there, so that gasket comes out before the screen goes in. Choose a 2, 3, 4, or 6 inch screen to match the vent size. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
Unlike the screened opening, the joints along the exhaust vent keep their rubber gaskets. The narrow pipe end slides into the wider end with 2 inches of overlap. A locking clamp supplied on the female end of each pipe and fitting secures each exhaust joint. A qualified professional installs the vent, and DuraVent recommends a yearly check.

The DuraVent PolyPro Bird Guard Screen ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
