U-Bolts
Stronger than routing clamps and hangers, U-bolts support heavy pipe, tube, and conduit from ceilings, walls, and poles. Galvanized steel U-bolts have better corrosion resistance than black-oxide and zinc-plated steel U-bolts.
U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.

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. Use them to support heavy pipe, tube, and conduit from ceilings, walls, and poles. All include four nuts to allow fastening from the top and the bottom.
Galvanized steel U-bolts have good corrosion resistance in most environments.
