This kit is only compatible with the Pro 100 EXP Stage 1 and Stage 2 (2.3–27.2 kg) dumbbells.  If your dumbbells say Pro 100 EXP and currently max out at 27.2, this kit fits. 

It will not work with any other PowerBlock models.  Check compatibility here.  If you are unsure of compatibility, please contact customer service.
