I'm wanting to cut a couple of holes in my concrete floor and install some 2" receiver hitch tubes in them to be able to install and remove some portable stands. The problem is that there is a bit of play in 2" O.D. square tubing, and that play is accentuated the longer the inserted tube gets. Without cutting (and keeping) a much larger opening in the concrete to allow for the installation of some tightening bolts, does anybody have any ideas to accomplish this project?
Thanks in advance.
