Model EFJ-437-HP extruded aluminum louver 4" deep • 37½° high performance J-blade


The EFJ-437-HP blends the aesthetic appeal of a non-drainable blade with the higher water penetration protection of a drainable blade louver by incorporating a drainable head member to capture water that cascades down the face of the building and channeling into downspouts and away from the airflow paths.
