The Barbell Holder is a vertical bolt-on bar cradle that mounts directly on the exterior of your T-3 or X-3 Series Power Racks and the Elite Series Mass Storage System. Installation is quick and easy, with a streamlined two-bolt design. This convenient barbell holder will store your favorite Olympic-sized bar into the bar holder's 8.5" tall seamless steel tube, protecting the knurling of your bar by only holding the sleeve keeping your equipment fully upright and safely stored.
