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. 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—Galvanized steel U-bolts have good corrosion resistance in most environments.

304 Stainless Steel—304 stainless steel U-bolts have excellent corrosion resistance and good chemical resistance.
