Parallel Beam-to-Beam Clamps

Join two beams in a straight line without drilling or welding. The bolt can be removed to insert threaded rod.
Zinc-plated iron clamps have mild corrosion resistance. Galvanized iron clamps have better corrosion resistance than zinc-plated iron clamps.

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. 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.
U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.
