The 8mm (5/16") Original GymPin Cable Stack Extender (GRADE B) Designed to be a universal fit for all pin loaded machines that use an 8mm selector pin, you should have no problems adding weight to your chosen machine and adding tissue in the process. Designed and Manufactured in the UK using the finest quality materials and stringent quality process. It began with some brilliant British ingenuity, some great craftsmanship and 300 prototypes later, The Original 2″ GymPin was born. The limitations we found in our local gym were too much. Not enough resistance and certainly not enough to push us to our limits. When we spoke to others on the scene, they were the same. They wanted more from their gym equipment and needed a solution. Now you can build muscle using the kit that you have access to. Orders are usually dispatched within 1-2 days.

This is just what I needed. Doesn't weigh much either! Great job GymPin, this stays in my gym bag now :)

This gympin combo has transformed my workouts, I now use the cable machines that I used to stack again, now with added weight with plenty of room for more. The pair of machine extenders are great for leg day.
