Give children the thrill of combining both sensory and light. This handy cover fits over the top of larger sized Jonti-Craft light tables and has a see-thru bottom, which is especially great for exploring sand and light. It helps to protect the surface of the light table and the 3" tall side rails contain messy media. Plus, it fits over the edge of the light table to ensure a stable surface and is large enough to accommodate groups of children. 5-1/2"H x 44"W x 24"D.
