Builders Best 112425B Duraflo 4 Inches Roof Exhaust Vent Cap New Generation Black

Product Description

The Builders Best 112425B DuraFlo 4 Inches Roof Exhaust Vent Cap is a heavy-duty rooftop ventilation fitting designed for residential and light commercial applications. It is built from polypropylene, a thermoplastic material modified for impact resistance and UV stability. This means the cap holds up in harsh outdoor conditions including direct sunlight, freezing temperatures, and wind-driven rain without cracking or fading over time. The black finish blends with a wide range of roofing materials and resists color degradation from prolonged UV exposure. HVAC installers, builders, and contractors rely on this type of roof cap to terminate exhaust duct runs at the roofline, preventing backdrafts, pests, and moisture from entering the duct system. The 112425B fits 4-inch diameter pipe, making it compatible with standard bathroom exhaust fan duct runs and similar ventilation systems. The cap measures 13 inches in length and 11 inches in width, with a height of 5.875 inches, giving it a low-profile footprint on the roof deck. A removable grid or grill is included for use in bathroom exhaust fan installations to keep out debris and small animals. When the cap is used as a dryer vent termination, the grid or grill must be removed to prevent lint accumulation and potential fire hazard. Manufactured in Canada by Canplas and Ipex, this cap meets the quality standards expected on professional job sites. It ships as a single unit and carries a UPC of 662671074232. Prop 65 compliance is confirmed as not applicable. This roof exhaust vent cap is a straightforward, code-friendly solution for terminating 4-inch ventilation ductwork through the roof.
