Duraflo 60PRO50SLG 50-Square Inch Weatherpro Slantback Roof Vent, Gray [並行輸入品]

商品説明

Miami Dade High Velocity Hurricane Zone certified. With the WeatherPRO Series PRO Slant Back you no longer need to worry about foul weather. The unique baffle system within the WeatherPRO Series PRO50SL wards off driving snow and blistering rain while allowing warm moist air to exit in a chimney like fashion eliminating shingle stains. The Vent cap design with built in weeping holes eliminates bird nesting and water pooling while the flat exterior wall acts as the first line of weather defense by deflecting driving wind over the cap and not under it like many traditional vents do. Five PRO Slant Backs will ventilate approximately 1000 sq. ft. of attic space. Injection molded from pure, high grade polypropylene with premium UV inhibitor additives. Type B Roof Vent. NOA # 11-0930.08.
