We searched the internet for an umbrella stand to fit an umbrella pole that was a diameter of 1.9 inches.  The specifications on the website said the hole diameter and neck diameter was 2".  When it arrived, there was no possible way to fit it into the neck, even when we removed the two adapters for smaller umbrella poles.  That diameter was less than 1.9 inches.  Luckily, my husband owns a manufacturing business and they were able to retrofit the pole opening so we didn't need to return the umbrella stand...Maybe his manufacturing business should start making umbrella stands with 2" openings!!!  Otherwise, the rest of the stand was good quality.Pros: well madeCons: pole opening measurement not as advertised, so don't order it for the Umbrella!
