WeatherPRO® Technology was designed with the harsh North American climates in mind, allowing high airflow while providing excellent defense against weather infiltration. With no moving parts, the unique baffle system effectively deflects rain and snow, allowing water to drain harmlessly out of the drainage openings. Install the Duraflo® WeatherPRO Series PRO75 on a sloped, shingled roof to ventilate hot, moist attic air as a part of a balanced ventilation system. Installed within 24 inches of the roof’s peak.
