Model ECD-545-BL

Extruded Aluminum Blast Louver
5" Deep - 45 Degree Horizontal Blade

The ECD-545-BL offers exceptional protection against wind-driven rain under the most severe conditions and is ideally suited for high wind areas or applications that are sensitive to wind-driven rain penetration. The ECD-545-BL incorporates horizontal blades and is available in a wide array of anodized and painted finishes including custom color matching.

The ECD-545-BL louver is independent 3rd-party tested for blast resistance, meeting the requirements of GSA Condition 2 when exposed to peak blast pressures of 16.7 psi and impulses of 85.6 psi-ms.
