Product Review

The Lock-Jaw Standard barbell collar features a solid nylon resin frame and injection molded pressure pads, making it nearly unbreakable. The single-action cam lock securely clamps the collar once positioned on the bar. Lock-Jaw collars will withstand the toughest workout environments. Same design as the Olympic version, but this model fits the standard (1-inch) bars and NOT the 2 inch Olympic bars. 4 ounces per set.
