Model EFD-437-FL extruded aluminum louver 4" deep • 37½° drainable blade

Application

The EFD-437-FL 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 design is engineered and tested to withstand extreme loads, debris impact, and cyclic fatigue associated with the severe weather effects of hurricanes (Florida Building Code approval No. FL32498).
