Correct! It will also fit over two half-boxes side by side, obviously... It makes it nice and tidy that way.
Some pro tips and downsides:
-Make sure you put the finger hold of the bamboo on the outsides when you put the bamboo down, this will make a closer seal in the middle which is important if you decide to cut on the bamboo. You don't want whatever you're cutting to run into your dishes/stuff underneath.
-I now use the SP knife and cutting board on top of the bamboo on this prep table to prevent juices running...
-Keeping stuff that you have to access often under the bamboo kind of sucks. The bamboo is now dirty from prep and you're constantly lifting it to get access. That's why I leave my dishes under there as they are accessed less frequently, but now hang my silverware on the outside of the prep table as I'm constantly digging in there for knives, spatulas, etc, etc. It's not as compact as having everything underneath, but more handy.
-Add the paper towel holder to this prep table and you're golden.
