Ok, it works. I confess I didn't read the description of the product carefully, I assumed it would be plastic but found out that it's made of some kind of metal, so that's a pleasant surprise. It says it's 2 1/8 inches wide, I would say it's closer to 2 inches. I measured it on the scale which read a little under 2 but then it expands at the top bringing it closer to 2 1/8. I have been using a 2 1/8" hole saw on my desk and it is quite loose, I was expecting a tighter fit. Having said that I don't see anything wrong with docking it with a star, it fits even if it's ever loose, made of metal decent finish overall this is a decent product my house had built in desks in the bedrooms with hard panels that could run chords through the desk.
