About this detail

Refrigerant piping passes through a sixteen gauge galvanized steel sleeve in a face brick wall, secured with Hydra-Zorb or Cush-A-Clamp supports. Insulation is butted against the clamp assembly, with liquid and suction lines treated similarly. A one and five-eighths by one and five-eighths inch Unistrut channel is supported by a four by four by one-quarter inch angle anchored to the structure with one-half by three and one-half inch expansion bolts and welded on both sides. Trapeze hangers utilize galvanized hanger rods, nuts, and washers to support multiple copper, plastic, steel, galvanized, cast iron, and insulated pipes using engineered strut channels and pipe clamps with elastomer cushions and calcium silicate shields.
