Marsh's 5' High Pro-Rite Magnetic Markerboard with Aluminum Frame is a full foot taller than typical whiteboards, so it's perfect for users in wheelchairs or early-learning classrooms. The durable porcelain-on-steel board has a 50-year warranty and resists scratching and ghosting. The aluminum frame and half-inch thick fiberboard backing keep it strong and sturdy. Attach magnets without fear of harming the surface.
