I am the owner/ head coach here at CrossFit 828 up here in Boone, NC and I've got 4 of these here in my box with the escalating pull up bars, chambered pull up bars, pegs, and monkey bars attached. These racks opened up an enormous amount of opportunities for variability in the workouts for my box and with all the attachments allowed plenty of space for any number lifts taken from a rack, banded lifts, mobility work, and ring or bar gymnastic movements. On top of this they are solid as can be, can handle as much weight and as many people as you can fit on them and do not flex or budge at all. I highly recommend these for any CrossFit facility or power gym.
