Roller J-Cups Strengthbae – J-Hook Roller untuk Power Rack 60 × 60 dan 75 × 75 mm

Roller J-Cups allow users to adjust the barbell's position without having to repeatedly lift and reset it. Once the barbell is placed on the J-cups, the bar can be slid across the rollers until the center knurling—or the midpoint—is aligned as desired. This feature is particularly useful for the bench press, where the barbell needs to be centered relative to the bench. The rollers also assist during squat setups, especially after weight plates have been loaded and the barbell becomes more difficult to shift manually.
