Model EFD-645 extruded aluminum louver 6" deep • 45° drainable blade


The EFD-645 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 EFD-645 is available in a wide array of anodized and painted finishes including custom color matching.
