DuctSox
OvalSox is designed for low clearance HVAC ventilation ranges from 11- to 22-inches high and 47- to 93-inches wide, and saves 13 to 27 inches of headroom versus round HVAC fabric and metal duct alternatives. Retains an inflated shape even during idle air handling periods with polyester ropes and supportive fiberglass rods for structural integrity.
