Michael's review of Custom Rectangle Magnets
Carstickers magnets for electrical panel schedules is the way to go. No messing with tape, glue or adhesive card holders, they not only don't permanently obscure the factory installed labels, but changing them out for an updated version leaves no adhesive scars or torn paper. And the printing is of higher quality than any paper printer I've ever owned. For the first time, the colors of the printout match perfectly with those on my pc screen. Wish I had thought of this years ago.
