Build one of scrap 2x4, etc. and used aluminum screen wire. ONLY problem was, I built it about 1 inch too small, as I didn't allow for the wire sticking out on all sides. USE IT FOR FLASHLIGHT BATTERIES, FLASHLIGHTS, etc.

Had a professional metalworking company make an all steel box, and told the guy ahead of time, if a cell phone or radio was placed inside, it couldn't ring OR play when the lid was placed on top. Man placed his cell phone inside the day it was done, called it and NOTHING happened. However, cost me $700, but my generator DOES fit inside, on top of some bottom/side shielding rubber mats from WalMart ... another $50 !
