Bakers Racks made of Titanium, supper light and strong. 7 racks, 84", 86.5" and 88", 14 shelves per rack 44" x 30". I also have a few hundred plastic bread trays that fit in the racks. Would work well with 22"x30" serving trays for cafeteria hall or kitchen, or plywood shelves for portable storing of parts or products. 4 heavy duty swivel casters with wide wheels made for easy mobility from one area to another. Costs over $2000.00 ea new. Asking $200 each.
