The McGill 3/4 Inches (29mm Outer Diameter) Loop Hanger is a pipe attachment designed to suspend stationary, non-insulated pipelines.¹ Typically made from zinc-coated or galvanized steel for corrosion resistance, this hanger loops around the pipe to provide support.² It often features a keyed insert nut for easy height adjustment using threaded rods and is recommended for reliable and secure suspension of various piping systems. These hangers are common in mechanical and electrical installations.
