Pipe & Conduit Supports
Material: Atkore pipe clamps, unless noted, are punch- press made from hot-rolled, pickled and oiled steel plates, strip, bar or coil, and conform to one or more of the following specifications: ASTM A1008, A575, A576, A635, A1011 SS GR 33, A1011 HSLAS GR 45, A1046 or A36. The fitting steel also meets or exceeds the physical properties of ASTM A1011 GR 33. The pickling of the steel produces a smooth surface free from scale. Many items are also available in stainless steel, aluminum and fiberglass. Consult factory for ordering information. Finishes: Pipe supports are available in: ꞏ Electro-galvanized (EG), conforming to ASTM B633 Type III SC1 ꞏ Hot-dipped galvanized (HG), conforming to ASTM A123 or A153 (hardware) ꞏ Green Powder Coat (GR), conforming to commercial standards for Powder Coating, and plain (PL) ꞏ Unistrut Defender (DF), conforming to ASTM A1059 or A1046 Application: Atkore pipe clamps, pipe hangers, brackets and rollers are designed for the support of electrical and mechanical services. Supports to meet nearly every requirement can be attained using Atkore Metal Framing components.
Dimensions: Imperial dimensions are illustrated in inches. Metric dimensions are shown in parenthesis or as noted. Unless noted, all metric dimensions are in millimeters and rounded

Note: When tightening 1 ⁄
4 " screws used with a two piece pipe clamp, a torque of 5 foot
pounds (60 inch-pounds) should be used.
Design Load: Design load data, where shown, is based on the ultimate strength of the connection with a safety factor of 5.0, unless otherwise noted. When used for mechanical supports, load capacities of brackets, fittings and other supporting elements should be in compliance with the American Standard Code for Pressure Piping.
