I worked 25 years for a Major Car manufacturer's Design office. Since we used to do everything by hand with blueprints and sketches and we had tons of these flat file drawers. One day the color and materials girl who was responsible for the new car colors decided she wanted a bunch of them for her new area but they were the "wrong color white" for her area. Now we had a massive paint booth for spraying the car designs but instead of repainting them they took a fork lift and started dumping them in the 40 yard haul off dumpster. I backed up my truck and told them start dumping them here and got 8 or 9 of them in several trips. Ours were 4ft wide and 3ft deep with 5 drawers for Architectural "E" size sheets. They are indeed awesome for keeping sorted slabs, mineral specimens, cabs, pretty much anything. They are built strong and will carry a ton of weight without drawers sagging etc.. Love em and agree if you ever see any grab them as you will love them.
