Description
A frame constructed of strut and MIRO’s patented bases are used to support duct on flat roofs. Unique design allows a sturdy support without penetrating or causing damage to the roof membrane. Ducts rest on a 14 gauge channel and are adjustable in height and width. All 4-DSA models are manufactured in a 14 gauge telescoping design for maximum adjustability in length and height. The bases are polycarbonate plastic and all other metal parts are made of hot-dip galvanized steel.
