Use your pipe, tubing, or conduit trade size to find a U-bolt that fits.
Clamping U-Bolts
 |
With Steel and Stainless Steel Mounting Plate |
Also known as muffler clamps, these U-bolts have a rounded mounting plate that fully surrounds pipe, conduit, and tubing for a secure fit. Stronger than routing clamps and hangers, U-bolts support heavy pipe, tube, and conduit from ceilings, walls, and poles.
Chrome-Plated Steel—Chrome-plated steel U-bolts are more corrosion resistant than zinc-plated steel U-bolts.
