Model EJ-637-HP

Extruded Aluminum Louver
6" Deep - 37-1/2 Degree High Performance J-Blade

The EJ-637-HP blends the aesthetic appeal of a non-drainable blade with the higher water penetration 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. The EF-637-HP is available in a wide array of anodized and painted finishes including custom color matching.
