With the CAP Barbell 2" Chrome Spring Clip Collar with Plastic grip, weight plates stay in place while you work out. These Clip Collars fit all Olympic weightlifting bars. Featuring a smooth chrome finish that protects the collars from rust for years to come and plastic covers for the handles, providing a secure grip, making it easy when placing the collars on or taking them off the bar. While mostly used to secure weights, these collars can also add to your workout, as you can squeeze the weight collar handles in different grip formations in-order to work out your forearm muscles and improve hand grip strength. At only a few inches tall, the CAP Barbell 2" Chrome Spring Clip Collar won't take up much room in your at-home gym and can easily be carried in a gym bag to an outside weight room.
