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

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

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).

First off, know the size of the holes of the machines you’re using. Simple google search helps, I learned Planet Fitness USUALLY has 8mm machines. This tool is perfect, low price and good quality! Can be too big/long for some machines so use common sense on where and what you’re trying to use it on.

After reading the somewhat good reviews I decided to purchase this item. NEVER AGAIN!!!!!!!! It broke on the first use with a measly 50 pounds. DON’T BUY!
