Roller J-Cups

The Roller J-Cups makes aligning the barbell much easier. When racking the bar onto the roller, the roller slides the bar into the perfect position, and then the lifter can easily position the bar from side to side to center the bar in the Power Rack. Each J-Cup fits securely in place so you can focus on your workout without having to worry about the possibility of hook slippage or movement. Featuring heavy-duty nylon rollers and UHMW plastic on the backplate, lip, and frame, helping preserve your bars knurling and rack from being damaged. Additionally, the Roller accepts all bar sizes from standard to large squat bars.
