Awesome rack! Free shipping, delivered within a week of ordering, and quite easy to assemble (took like 30 minutes). After assembling, I lined it up on the wall and my buddy bolted it into the concrete. Didn’t use stringers and this thing doesn’t budge. I’m 230 pounds and have no concerns about it coming off the wall doing pull-ups, squats, etc. My only qualm is there is no wiggle room to lift it a little while unfolding, so where you mount it is where the legs stay. So I fold it out, instead of in to close, so it rests on my mat when fully extended.
