"I bought a lot of these to make a couple of "cages" above raised gardens to keep out deer, squirrels, and birds. They are large boxes, wrapped in poultry fencing, with swinging doors. Very solid, so I expect they will hold up to occasional falling branches from an overhanging cottonwood tree. All the parts except the fencing and the 3/4" EMT came from MakerPipe. EMT is cheap and strong (steel pipe), and the MakerPipe connectors are a handy and flexible way to make use of it." - Sam
