About this detail

This rooftop equipment isolation assembly rests on a tubular steel main frame supported by the roof deck. A freestanding spring with a neoprene acoustical seat sits inside the frame, carrying a downward acting adjustment bolt through an impact casting and neoprene bushing. A continuous wood nailer and wooden port frame flank the assembly, topped with a cover plate, cant strip, insulation, and roofing. An aluminum weather seal and air seat interface directly with the bottom of the rooftop air conditioning unit, secured by a spring loop and stabilized by a cross brace.
