48.5" x 144.5" Aluminum Frame Porcelain Magnetic Whiteboard, 1 Marker, 1 Eraser. Offering a superior writing surface and unsurpassed durability, Ghent's porcelain magnetic whiteboards were made with our customers in mind. The 28-gauge porcelain-on-steel surface is mounted to a 3/8" backing for extra strength. The durable porcelain enameled surface keeps the dry erase board from scratching or denting, even when installed in high-traffic schools and offices. The wear resistant surface does not absorb ink, eliminating staining and ghosting that would otherwise result from repeated use. The easy to wipe surface requires less cleaning, achieving a long-lasting bright white surface without the hassle. Ghent's magnetic whiteboard can be used to post bulletins without worrying the announcement will be erased and includes a black marker and eraser. Each board comes in our sleek satin aluminum frame and includes our detachable SmartPak tray that reduces waste and damage during delivery. Ghent's porcelain magnetic whiteboard carries a 50-year warranty and is made in the USA.
