4SEASONS PRO
Designed for steep-slope roof applications, the 4SEASONS PRO features a uniquely engineered profile that helps block wind-driven rain and snow from entering the attic. Its sloped hood efficiently deflects running water, enhancing protection in harsh weather conditions. Built for performance in extreme climates, this vent operates from dawn to dusk, even in low-light conditions and continues to function as a high-capacity, weather-resistant passive vent after sunset.
