You guys who think you can successfully straighten a piece of bent angle so it looks new have obviously never tried it. In order for angle iron to bend, one side has to stretch the steel, so getting it back straight means you have to stretch the other side the same amount which would then make the piece a bit too long. Yes you can untwist it and maybe make it work enough so he could hook up to a QA attachment with a little beating an banging, but to make it back to the original dimensions is going to require cutting and replacing that piece. So I would put back a much stronger piece when doing that. A boxed tubing in .250 wall or thicker would be my choice.
