The GearUp Pro J-Cups can be attached to your rig and work as a support for your barbells (e.g., for squats, overhead presses).
They have plastic on both side to offer protection not only for your barsbut for your uprights as well. Moreover, they have plastic coating on the sides so as not to scratch your rig whenever you remove them and place them elsewhere. The Pro J-Cups by GearUp can handle extreme amounts of weight. Designed to handle loads of up to 3000 kg.
