About this detail

Round and rectangular HVAC ducts are hung and braced using threaded rods, trapeze hangers, and steel bands or straps secured to the structure above. Double nuts secure the threaded rods, and seismic braces are added where required per ASCE 7-10 Section 13.6.17 and SMACNA guidelines. Strap and support spacing is maintained at four feet on center. Manufactured support and bracing components such as Tolco, B-Line, or Afcon are used in accordance with structural connection details.
