Fits 2" umbrella hole in a .22" to .25" thick glass or acrylic top.
Inner hole fits 1-1/2" umbrella pole.
Vinyl ring, plastic insert
How to install: Place the vinyl ring in hot water for 5 minutes as this will make the vinyl pliable for inserting into the table top hole.
Also, the old ring may be removed by carefully heating it with a blow dryer just enough to make it softer for removal.
