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.

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.

This is a pretty cool concept if you're looking to add a little extra weight to your stack of plates. The way it works is simple—just insert the pin into the stack, and you're good to go. The strong magnets at the base of the pin help secure it tightly to the stack, which gives you added peace of mind while you're working out. That said, it’s important to keep in mind that you can’t go too crazy adding weight. While it does hold up, I wouldn’t recommend trying to slap another 100 lbs on there. The pin is only 6 inches long, so to prevent the weights from sliding off, you’ll need to use a clamp. This does limit you to using mostly 45 lb or 50 lb plates, which is something to consider depending on your machine setup. I’d really only recommend this to people who are maxing out the weight stacks on their machines. There’s no real point in getting this unless you're consistently working with the heaviest available weights on your equipment. Also, one thing to note—if your weight stack has more of a curved face (as opposed to the typical flat face), it might be difficult to get a secure fit with this pin. Overall, it’s a solid product for those looking to push past their machine’s weight limits, but just be aware of its limitations before you buy.

Pin bent upon first use.

This is perfect for the gym! It is great quality (has some weight to it) and stacks plates with ease. Fits machines at the gym I go to :)

Most weight machines stop at fairly low max weight. This is a great idea to help increase the weight on the stack so long as you are not stressing the cables too much. It is very heavy duty, and fits Olympic plates nicely.

This thing is heavy duty I put two 45’s on it my concern is not the plate holder but the actual pin that goes into the stack it is a. It bit short so I’m not sure how much this can actually hold
