Model SFD-445 galvannealed steel louver 4" deep • 45° drainable blade


The SFD-445 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-445 is available in a wide array of painted finishes including custom color matching.
