I bought some “rescue tape†at Ace. Put the bottom section of your pole in the holder and grab the pole with your thumb marking the top of the hole. Pull it back out and mark your thumb location with a Sharpie. Dry off the pole and run two wraps of tape around the pole just below the mark. Test fit and see if that has tightened the fit up to your liking. Do the same at the bottom of the pole and that should eliminate play at the bottom as well. It’s a little trial and error, but I’ve got both my umbrella poles fixed this way.
