I have a like new pair of REP FITNESS PR-5000 Flat Sandwich J-Cups attachment. I did open them and put them on the rack, but didnt actually use them. One of the j-cups fits a bit snug, but doesnt affect anything. Im asking $70. They are intended for Rep Fitness Pr-5000 power racks. They might fit other 1 3x3 hole racks. These are heavy duty and of great quality. If interested text me at 83I-946-l83l or email. Open to possible trades for retro Nintendo stuff or Weightlifting equipment. Must pick up in Greenfield.
