Eleiko Powerlifting Competition Collars are carefully calibrated, IPF certified and beautifully designed chromed metal collars. Made for professional powerlifting, and ready for competition, the collars feature a ridged surface to ensure a secure grip when handling and are easy to operate with a quick turn screw fastening system to tighten down collars and keep discs in place. A protective inner liner is gentle on equipment, and a smart rubber inset prevents collars from “locking up.”
