The Olympic training collars offer a strong and secure fit on your 2” (5cm) Olympic barbell and dumbbell bar and provide quick and easy weight plate changes to let you focus on your reps. The collars ensure added safety during powerlifting, CrossFit, weightlifting and any other Olympic bar workout. They are easy to use and help to hold the weight plates firmly in place when the intensity of your training reaches its peak. The collars are easy to put on and off thanks to a bent ‘L-screw’, whilst a chromium plating guarantees enhanced durability. Plus, they feature a solid cast iron construction and come as a pair.
