As advertised. 2" hole saw and I measured and used a 2" hole saw with no problems. The part fits perfectly in a 2" hole. Perfect as a very inexpensive desktop hub for my computer and data cables. A good 1/4" hole. Even if you're not sure about your 2" hole, it will won't hit unless you cut a 2-1/2" hole. The top insert that snaps into the shell is in two pieces. The bottom has three different sized slots if you're really picky with your cables The top rotates to allow you to choose one of the three holes and helps close gaps if you use a slightly larger bottom gap than you need to replace.
