Tag: lock jaw collars

Olympic collars are clamps that are placed on the ends of an Olympic bar to secure weight plates to prevent them from sliding off. Often collars are an afterthought for those kitting out a home gym. Instead, lifters tend to invest a lot of money in expensive bumper plates and quality steel bars. However, you should remember that a good pair of collars can add huge value by limiting damage to your bumper plates and your barbells.
