We use standardized 2" powdercoated metal tubing for our dummy hitch. There is going to be some play or wiggle between our dummy hitch and a standardized receiver on a vehicle. If there were no play it would be extremely hard to get a hitch in and out of your receiver. Because FanPole is not the only product that deals with this issue there are some solutions out there.
Here is one on Amazon that you can try:
Hitch Tightener
This will take the play out from between our dummy hitch and the receiver on your vehicle.

We are currently looking at incorporating a solution into our FanPole.
