Got a call from a guy who owns a food import business. He has two coolers, 35' X 50' and 60' X 60'. Last weekend somebody stole his condensing units off his roof. Then they cut a hole in the roof and stole most of his wiring and copper tubing. I'm giving him a bid on replacing his refrigeration equipment and would like to bid some cages to protect his new stuff.

Does anybody have any experience building cages to protect equipment from thieves?
