OK i am gonna post some pics, i ordered the black one and it just drops down in the hole. I took some pics with a tape measure. Maybe we can come up with something, The one i tok ourt was black if that helps The White one fits perfect in the pole suport but the lip isnt big enough so it goes down in the hole, The Black one – way too small This 1st pic shows the black on, its not tight at all, just fell right down in there This one shows thew hole with the pole support brakcet down in there, the white one fits tight in the support pole but not a big enough lip to stay outside the hole HELPPPPPPPP
