About this detail

A suspended fan is supported by four five-eighths-inch hanging rods and diagonal one-eighth-inch aircraft cable sway braces attached to corners. The assembly mounts to the structure using one-and-five-eighths-inch by one-and-five-eighths-inch Unistrut channels secured with half-inch lag screws having a minimum two-and-a-half-inch embedment. Vibration isolators with a minimum two-inch static deflection and neoprene pads isolate the suspended equipment. Rectangular and round ducts are supported using one-inch by sixteen-gauge continuous collars drawn tight around the duct and hung with one-inch by sixteen-gauge hanger straps secured with sheet metal screws and three-eighths-inch bolts, nuts, and star washers.
