Good luck mounting those. I hope you have a lot of time on your hands. These are manufactured to be placed inside a specific hole cutout in a wood panel or metal door. I hope you like lots of sawing/drilling/filing.
If installing in a metal door with a cutout hole and you have to do filing, be sure to temporarily remove the coin acceptor and set it aside some place safe. The reason is that all the metal shavings/filings will stick to the magnet causing coin jams.
