How to do this yourself:
1. Drill three holes evenly spaced around the CD carrel, preferably with a 11/64 or 3/16 bit.
2. Hold the drilled carrel on the wall where you want it placed, and mark holes on the wall.
3. Drill a pilot hole in the wall.
4. Screw carrel to wall (I recommend using a plastic anchor).
5. Load with CDs.
