U-Bolts
Heavy objects are supported by U-bolts from ceilings, walls, and poles. They are more durable than routing clamps and hangers, and if constructed of galvanized steel or zinc-coated steel, they are corrosion resistant. For light-duty lifting, other types of U-bolts are made of aluminum, and other grades of stainless-steel U-bolts are chemically resistant. For a secure connection, U-bolts are secured with nuts.
