    With Plastic Mounting

    Plate

    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—Zinc-plated steel U-bolts have good corrosion resistance in most environments.
    4 Nuts Included—U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.
