Heavy duty slam balls i believe this is a white label product seen a few other companies with same quality. Buy them used for great price

Heavy and doesn't slide was a good purchase for the price but lever arms aren't used very much and these are the lower quality option

Not bad but there are better options for the same price if you buy when on sale

Very basic it definitely works so not a bad add on to your gym

Didn't need it until I sold it but found another hack would buy again

Got rid of it too heavy for the rows I wanted to use it for

Added this to my monkey bars at the top of my rogue rack

Had for a long time and never used tripped over it a few times finally sold
