Elite addition
These make doing overcoming iso's so much easier and protects your rack from the bar scraping the paint off. The ease of adjusting the height is the number 1 reason I want to outfit all my racks with a pair. I have athletes of different height working on one pair and it takes seconds to adjust the height.

The iso hooks are awesome
We had been looking for an isometric rack for a while but they’re very expensive. The hooks work just as well, don’t take any extra space (because you use them on an existing rack) and and easily adjusted for whatever isometric movement you want to perform.
