These clamps are made from pure nylon for maximum strength and have rounded edges that won't cut into wire. They also have a unique screw hole alignment locking mechanism that prevents them from twisting when tightened by a mounting screw. Resistant to solvents, oils, acids, and moisture. They absorb shock and vibration and reduces unwanted noise. Black clamps have a UV inhibitor added.
