Vibration-Damping U-Bolts
Reduce vibration and noise in your lines—a plastic cushion tightly grips pipe, tubing, and conduit to prevent movement. All have nylon-insert locknuts, which grip the thread to resist loosening without damaging threads. Use to support heavy pipe, tube, and conduit from ceilings, walls, and poles.
Zinc-plated steel U-bolts have good corrosion resistance in most environments. 316 stainless steel U-bolts have excellent corrosion resistance and chemical resistance.
