    Tightening a Receiver Tube

    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.

    Here is an idea I got from seeing how a bicycle handlebar is attached.

    Hope you can figure out how it works as my drawing skills are not so good.

    Red plate is tapped for the bolt while blue one has thru hole.

    Lots of work but it does take the play out of any attachment.

    It will require leaving a hole or provision to tighten up the clamp bolt in whatever fixture you attach the clamp to.

    The biggest problem with the receiver tubes is the factory ones went "el cheapo" and use 3/16 wall thickness tube instead of the old Reese 1/4" wall with the broached out seam weld on the inside. Thats why they went thinner wall so they wouldn't have to fool with the seam weld down one side...Bob

    Similar solution to what I suggested.

    i would use the hard plastic shims from home depot, they sell them for shimming doors, i always have them for leveling work and setting gapes, etc. they are the rite size to fit the tube and then remove as needed.

    I would make up the receiver setup with a plate for floor mounting. Drill holes for four 3/8'' drop in anchors with female threads. You could even counter sink the holes so when not in use bolts could be installed to be flush with concrete.

    Would it not be advantageous to modify the insert, rather than the receiver? I'd worry that the receiver would be over shrunk.

    The slop is max hundredths of an inch. I would recommend some old feeler gauges as shims that can be used as needed.

    The downside of a permanent fix, welding material to the insert is debris and rust making the fit a permanent one.

    great answer!!!

    Maybe weld on small tapered shims onto the same side on both male tubes to press the opposite sides snugly against the receiver tubes?

    Ditto, It doesn't take much to fill the gap. Worst case you tack on some thin metal strips to the tube.
