Any good hardware store should carry it. They usually stock the 3' height, but it also comes in 4'. It is galvanized, with 1/2"x1/2" square holes. It also comes in 1/4"x1/4" holes, but it is considerably more pricey. Just figure anything you can break or make a bigger hole with your bare hands, so can a coon! If you have any windows, they should also have this over them so the coon can't just climb in, or even lift a cracked open one. They are very crafty and persistent creatures, and will work at something until they can figure it out!
