U-Bolts with Mounting Plates
A mounting plate provides a more secure hold at the mounting surface. Stronger than routing clamps and hangers, U-bolts support heavy pipe, tube, and conduit from ceilings, walls, and poles.
Black-oxide steel U-bolts have mild corrosion resistance. Zinc-plated steel U-bolts have good corrosion resistance in most environments. Galvanized steel U-bolts have better corrosion resistance than black-oxide and zinc-plated steel U-bolts. 304 stainless steel U-bolts have excellent corrosion resistance and good chemical resistance.
U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.
