The Builder’s Best Duraflo Roof Cap Dryer Bath Exhaust Vent is a durable, non-metal vent designed to safely exhaust air from bathroom fans or dryers through the roof. It provides a reliable solution for home or light commercial ventilation systems where roof-mounted airflow is required. Constructed from heavy-duty black polypropylene plastic, the Duraflo vent features a seamless, leakproof outer shell that helps prevent water intrusion and weather damage. This 4-inch roof vent includes a back draft flapper that closes when the fan or dryer is not operating, preventing air and debris from entering the duct. A removable grid is provided for bathroom fan installations to keep out pests and debris; the grid should be removed when used as a dryer vent to allow unrestricted airflow. The Duraflo Roof Cap features an enlarged duct opening that meets code requirements and provides 15 square inches of net free area without the grid installed, ensuring efficient exhaust performance. Nail marks on the flange make placement and installation faster and more accurate, providing a secure, weather-resistant fit. Engineered by Builder’s Best, the Duraflo Roof Cap Dryer Bath Exhaust Vent combines durable construction, proper airflow design, and dependable function for safe and efficient home ventilation.
