Greenheck
The AFL-501 aluminum blind with 5.5 inches deep, protects the penetrations of the exterior in the FEMA 361 or 320 standards, to be complements in shelters or security rooms.
The blind manufactured by Greenheck has a design that incorporates the blades with an inverted V style that provides a greater free zone, excellent resistance to water penetration and low resistance to airflow, while providing maximum protection against extreme air loads and wind debris.
Licensed to carry the AMCA seal for Water Penetration and Air Performance, the AFL-501 UL-classified model can withstand wind loads up to 300 PSF and passes the ICC 500 debris standard of 15 lbs. 2x4 traveling at 100 MPH.
