Aria Low-Profile Glass Whiteboard achieves the look of weightless, floating glass. No visible hanging hardware or stand-offs allow the beauty of the frameless glass to complement any decor, creating an unobstructed writing surface. Heavy-duty hanging system promotes security and confidence in the installation. Hang your board horizontally or vertically on a variety of surfaces such as drywall, concrete or brick. Premium, 1/4" thick tempered glass floats just 1/2" from the wall without bowing, straining or moving. Use it as a single board for personal offices and conferences rooms or to create a glass whiteboard wall by lining up multiple glassboards in a row. Lower, steel support bar doubles as storage for your magnetic markers, keeping the writing surface free from clutter. It comes with four markers and an eraser.
