I have a T-3 Foldable Rack and was worried this Lever attachment wouldn't work (all the photo have the attachement being used on a standard squat rack, not foldable). I'm happy to report it does work, however I do have to be a little more nimble in moving it around because of the large bolts at the top and bottom that (for a lack of words) keep the rack bolted into the wall. I was really hoping to also purchase the leg press attachment, but there is not enough room behind / in the rack (from the wall) to be able to do presses (so that is a minor bummer, but nothing to blame Titan for). Would definetly recommend adding to any home gym.
