U-Bolts

U-Bolts

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

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

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

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 dissemble it.

Vibration-Damping U-Bolts

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.

Standoff Brackets

Standoff Brackets

Combine with a U-bolt or routing clamp to convey a variety of material, such as pipe, tubing, and cable raceway, at distance from floors, walls, and ceilings. The extra clearance allows access for maintenance and adding and removing lines.
