After reading many reviews of similar products, I found that a common problem was that the case was not the correct size. I ordered the 2" version and it fits snugly in the hole created by my 2" hole saw. I was a little worried that it wouldn't fit all the cables I needed to route, but it fits 4 power cables or ethernet gauge in the largest setting. Not sure which would be better. It's also nice that you can order one instead of multiple packs if you only need one.
