I am sure I am not imagining it, but does anyone recall a tool storage system that was not a traditional box with drawers, but was instead a clam shell type case that stood vertically and had a peg board to hook style hanging system and you’d hang your tools? The two opening halves had casters, had hinges in the back, you could open and close it and I believe it was silver, maybe aluminum exterior. Almost like a giant aluminum carry on luggage except with hanging tool storage? Dying to recall what they were any help appreciated.
