Model EXA-645-MD aluminum combination louver 6" deep • 37.5½° - 45° combination blade


The EXA-645-MD is engineered and tested to withstand extreme load, debris impact and cyclic fatigue failure associated with the severe weather effects of hurricanes (Miami-Dade County approval #16-0824.04). The design features stationary drainable louver blades to protect against water penetration and an integral airfoil blade control damper to allow positive shut-off of air intake and exhaust openings.
