Model ECV-645-MD

Extruded Aluminum Louver
6" Deep - 45 Degree Vertical Blade

The ECV-645-MD is engineered and tested to withstand extreme loads, debris impact, and cyclic fatigue associated with the severe weather effects of hurricanes (Miami-Dade County approval #21-1122.03). For installation, the ECV-645-MD is available either with standard continuous angles or with an optional factory installed sleeve which eliminates the need for direct anchorage to the substrate.
