Weight Stack Gym Pin Extender, 6", Ø 8 mm and Ø 10 mm, Cable Weight Machine Attachment, for Weight Lifting & Strength Training Allowing Additional Olympic Weight Plates, CNC-Machined Aluminum Bar.

I have one of these and one of the original king pin. This one is my favorite. It has great weight capacity and the magnets make it more stable. One of my cable machines feels off balance with just one of these so I got a second to balance the other side. That one is another brand without magnets and can start sliding out so I had to buy magnetic collars to hold that one in place. This one has no such issues. The max I've used on this is 45lbs but none of my issues were due to this. I should've gotten this for my second one. Well worth it.

I am still looking for the perfect extension pin for my weight stack. this one has a good sturdy build. My weight stack has 10mm holes, the 10mm pin does not go into the holes, the 8mm pin sits to loose and the magnets are a good addition for up to 10lbs going above that or hanging a 20lbs bumper plate on it pulls it away from the stack as you exercise, which leads to an imbalance of the weight stack really quick. Adding the maximum posted weight to the pin does not work, I put 2 45lbs bumper plates on it which is 40lbs under the max weight and the pin pulled out of the stack and got bent.

I started using this once my back got too strong for my cable machine, and I can't find much wrong about it. At first, I bought the wrong size (my fault), but it eventually got sorted out with an amazon refund. For my Force USA G-15 Pro, you should go for the larger size and it will fit well. It's nice and sturdy, but don't put too much weight on it or it might bend. I'd recommend staying under a 45lbs/20kg plate and you'll be fine. It functions well, and it's an "alright" value for money.

It works, keep in mind when you order this one pin by itself is 5lbs. If you plan on bringing it on a gym bag it will be hefty. For the casuals this might be way too much to do, however it has a place in the fitness world if you just need that extra pound where some machines do not have additional 5lb weight incrementation to it.
