For a dry erase board that withstands the test of time, there is simply no better choice than our porcelain steel markerboard surface. A layer of low gloss magnetic steel is laminated to a 7/16" thick MDF substrate for superior strength, durability, and moisture resistance. The surface is specially engineered to create greater color contrast with dry erase markers, and to provide smooth writability and easy erasability with no ghosting. Porcelain steel also offers reduced surface light distortion which enhances visibility to provide optimum eye comfort. Trimmed in anodized aluminum, the boards include a full-length tackable map rail and a full-length accessory tray with protective Dura-Safe rubber end caps. Mounting hardware is included.
