Model SFD-635 galvannealed steel louver 6" deep • 35° drainable blade


The SFD-635 formed steel drainable blade louver is designed to prevent water penetration in non-wind-driven rain applications by collecting water in frame and blade gutters and channeling it into downspouts and away from airflow paths. The SFD-635 is available in a wide array of painted finishes including custom color matching.
