We have a couple of OEI "Series XXI"5-drawer vertical file cabinets for $75 each. These commercial cabinets currently retail for over $1000. The cabinets measure at 15"W x 27.5"D x 59.25"H. They are made of light gray colored steel. They are letter size and each have a sliding panel to keep files near the front as you fill them up. These don't have rails but you can easily find those in most office supply stores or just use the sliding panel. These all have a lock and key. Each drawer has a label holder. The cabinets are in really solid condition with just some minor cosmetic wear to them. Recycled Furniture here in Irving has these and many other types of files cabinets to look at. Feel free to contact us for more info.
