About this detail

Ductwork is suspended using strap hangers, trapeze hangers, rods, wires, or straps secured with load-rated fasteners. Strap hangers maintain a maximum spacing of sixty inches with a one-inch minimum clearance, and screws may be omitted if hanger loops are placed under bottom reinforcement. Trapeze hangers utilize straps, angles, and rods sized according to the imposed load. Round duct supports incorporate wire bands matching the hanger strap size for diameters up to ten, twenty-four, and fifty inches maximum, ensuring hangers do not deform the duct shape.
