Customize your classroom or office with one of our versatile graphic boards. Plan, schedule, and forecast more efficiently every day. Our stock-graphic markerboards feature permanent ceramic ink graphics that have been fused to the surface for long-lasting durability. These boards save time and enhance learning in any classroom by presenting clearly visible lines, maps or grid patterns. Markerboards are porcelain steel and offer the same 50-year warranty as our other porcelain surfaces. Boards include a map rail and full-length accessory tray with new safer silicone rubber Dura-SafeTM corners.
