So I ordered this thinking two pieces meant I had two table hubs. When I only received one jack I went and ordered another one because I needed one. Imagine my surprise when the second sleeve is so different from the first! The first bushing I got was one piece (not two piece) so the hole didn't rotate. The second sleeve was in two pieces, so the hole rotates well. The material also seemed a little different; The second case appeared to be higher quality metal and shine a little more, although both are pretty good. While I probably got the wrong grommet the first time as it was only one piece and not two, I'm still giving this one 5 stars because they are both honestly good grommets. If I only needed a jack, I wouldn't understand anything. The second is definitely better than the first. So if you are looking for a little more shine and a prettier hinge I would ask them to send you another one. I drilled a 2.5" hole with a medium sized Ikea FIXA hole saw. Hole in chipboard (IKEA Linnmon) and it fits perfectly.
