All of you who are familiar with the KingsBox Combo PL Bench have surely also come across the supports for the Olympic barbell with a roller. However, if you have not, we now present them to you as a stand-alone product: the supports allow you to easily move the barbell sideways. Placing the barbell correctly on the structure is easy – as long as there are no heavier discs involved. The simple task would in that case take a lot of energy, which could have been preferably spent on a single lift.The KingsBox Mighty Roller J-Cups are attachments suitable for the Mighty series of structures.
