Weight Stack Pin and Spring Collar Weight Stack Extender Pin Commercial and Home Gym Accessories for Cable Tower and Functional Trainer Machine

Bought to add weight to my cable stack. Works good.

This is an excellent product that met my expectations.

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.

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.

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

Goes into stack. Holds weight. Pretty straight forward. I've added 90lbs with no issues.

This weight stack pin works fine but I've marked it down because the small pin that inserts into the stack started to bend after a couple of months of use with two 45lb plates making the product a bit unsafe. I've now purchased a different brand to try.

Works just fine I haven’t loaded it up with too much weight I stick to 20-30 pounds. For my needs it works ok

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).

Broke under thirty fives wouldn’t recommend
