The one-piece body is constructed of high-density (.187" thick) polyethylene allowing the cabinet to safely store acids and corrosives near your work area (including nitric and sulfuric acids). Double-wall recessed doors help to control vapors. Fit two cabinets in a 30 gallon cabinet or three in a 45-gallon cabinet. Labels read, "ACIDS/CORROSIVES" and display the international symbol for Corrosive Material. Shipped assembled and ready to use.
