Clamping U-Bolts
With Steel and Stainless Steel Mounting Plate
With Plastic 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.
Zinc-plated steel U-bolts have good corrosion resistance in most environments. Chrome-plated steel U-bolts are more corrosion resistant than 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.

Vibration-Damping U-Bolts
Reduce vibration and noise in your lines—a plastic cushion tightly grips pipe, tubing, and conduit to prevent movement. All have nylon-insert locknuts, which grip the thread to resist loosening without damaging threads. Use to support heavy pipe, tube, and conduit from ceilings, walls, and poles.
Zinc-plated steel U-bolts have good corrosion resistance in most environments. 316 stainless steel U-bolts have excellent corrosion resistance and chemical resistance.

Anti-Rattle Hitch Clamps
Stabilize your hitch for safe, quiet towing—these clamps strengthen the joint between the hitch insert and receiver to prevent rattling and swaying. Slide the U-bolt over the hitch insert and attach the mounting plate to the bottom using the included nuts. Tighten until the mounting plate presses firmly against the hitch insert and receiver.
