Round and rectangular HVAC ducts are suspended using load-rated hanger straps and bands of the same size to avoid disruption of duct insulation. Round ducts utilize slings secured with load-rated fasteners, while rectangular ducts are supported by straps fastened with screws and maintaining a one-inch minimum clearance. Typical seismic support bracing is provided at angled intervals across the suspension system.
