The Weight Stack Pin Extender is designed for users who’ve outgrown their built-in stack resistance. Simply insert the extender pin into the selector stack and load Olympic weight plates onto the end—adding up to 130 lbs of additional weight. It’s ideal for exercises like lat pulldowns, rows, and triceps pushdowns where more resistance is needed.
When not in use, the extender features a quick pin-in design for clean storage—just attach it to the top of your guide rod. Compatible with Major Fitness’s B52 Pro and F22 Pro machines, this attachment adds strength potential without adding bulk.
