Finally found a fit...FNTEK works well
Good design fits well. I had to return other products multiple times for not fitting the plates-being too big. The FNTEK works well, bought another. Highly recommend.

This works great to add serious weight to your light stack.
This is great. I have a relatively light stack, and I needed to add 25 to 35 pounds for heavy back pulls. Feels like it is made from quality material and does the job. I wasn't sure about the pin size, so I got the smallest one and only needed to wrap a little bit of electrical tape around it so it fit more snugly. If you are a powerhouse and need to add serious weight to your puny stack, buy this right now and go pump your muscles you gurley man!

This is an excellent product that met my expectations.

Wobbly
This might end up working, but its really loose in a weight stack. Could fall out with weight on it

Gets the job done.
Had to cut it down because it falls out of weight stack and throws off the balance but overall not bad.

Gym Pin
Perfect for adding more weight

Does not stay in place.
Terrible. Does not stay with the stack. Falls out after 1 rep with a 45lb plate. I purchased the largest one that I could buy. I had to use some pull-up assist bands to help hold it in place. I believe the pin need to be a little thicker and longer.

Get it now if you want to be stronger
Goes into stack. Holds weight. Pretty straight forward. I've added 90lbs with no issues.

No problems what so ever and can hold 3x 20kg plates without bending

I ordered 2 of these and they both have their insertion pins are at a slight angle (not straight). They still do the job on my Inspire Fitness SCS (10 mm dia. X 110 mm long).
