Based on the simple lever principle, the Rug and Rig Barbell Jack provides an efficient solution to loading and unloading weight onto your Olympic Barbell. The Jack raises the bar off the ground, allowing you to slide your Olympic Bumper Plates on and off.
The product is lined with a protective layer ensuring the safety of your barbell and its knurling.
For the most effective leverage, use just inside the shaft next to the side you want to exchange.
