Selecting U-Bolts Using Pipe, Conduit, or Tubing Trade Size

U-Bolts

Mount these general purpose U-bolts into an existing bracket, or combine with a mounting plate for a secure hold at the mounting surface.

U-Bolts with Mounting Plates

A mounting plate provides a more secure hold at the mounting surface.

U-Bolt Mounting Plates

Add a mounting plate to your U-bolt for a more secure hold at the mounting surface.

Square U-Bolts

Suspend and route flat-bottomed objects such as strut channel and small duct.

Clamping U-Bolts

Also known as muffler clamps, these U-bolts have a rounded mounting plate that fully surrounds pipe, conduit, and tubing for a secure fit.

Rubber-Cushioned U-Bolts

A durable rubber cushion and mounting plate prevent corrosion and wear caused by metal-to-metal contact. The mounting plate is removable, so the U-bolts can be installed onto an existing line without needing to disassemble it.

Vibration-Damping U-Bolts

Reduce vibration and noise in your lines—a plastic cushion tightly grips pipe, tubing, and conduit to prevent movement. Nylon-insert locknuts grip the thread to resist loosening.

Rubber-Cushioned Square U-Bolts

Reduce vibration and prevent metal-to-metal corrosion on flat-bottomed objects such as strut channel and small duct.

Beam Clamps for Strut Channel

Support strut channel at a right angle to the beam.

Wire Rope Clamps

Cast Wire Rope Clamps—Not for Lifting

Use in noncritical applications, such as fencing, where the strength of a forged clamp is not required. Install clamps so the saddle is on the long (live) end and the U-bolt is on the short (dead) end. They’re also known as wire rope clips.

Forged Stainless Steel Single-Saddle
Wire Rope Clamps—Not for Lifting

These clamps have a forged fabrication and are reliable in critical applications. They are not for making slings. These must be oriented with the saddle on the long (live) end and U-bolt on the short (dead) end. They’re also known as wire rope clips.
