For the mighty and royal series of rigs and racks, we developed the new barbell holders: Roller J Cups. They are very similar to the basic and well-known j cups, but on the main part, they have a plastic roller that enables moving the barbel horizontally.

The main benefit of this roller is the ability to adjust the barbell in the central position right before performing the lift. When using the normal J cups, it is possible to damage the barbell while adjusting it, so if you get the roller J cups, you don't have to worry about that.
