I got them at Home Depot. They have both black and green. They were in the plumbing section by the drains and piping. Sorry I don't have the part number but they are are 4.5 inches in diameter and the pipe part extends about 2 or 3 inches which I had to cut off with a dremel.
Thanks! I'm using a black bookcase, so I'd prefer the black over the white too. I'm toying with the idea of using pegboard instead of the cardboard backing though, and that would eliminate the need for vents. But then again, my house is quite cold in the winter and I'd like to limit the excess airflow... decisions, decisions!
