Need more weight for your toughest sets? The Major Fitness Weight Stack Pin Extender lets you go beyond the default weight stack limit—adding up to 59 kg of extra resistance using standard weight plates. Built for serious lifters and progressive overload, this smart add-on gives you more training capacity when it counts. Note: Only fits B52 PRO/F22 PRO. If your equipment is the B52 Standard or F22 Standard model, and you’ve already purchased our Weight Stack Set, this Weight Stack Pin Extender is also compatible for use. Show more
