Open sesame! This versatile all-in-one storage center organizes and stores tons of art, sensory, STEM or Maker supplies and materials for classroom activities in a compact and secure cabinet that also provides an ingenious work surface for the teacher. The main cabinet is stationary on floor glides and features a top section with one fixed shelf under one adjustable shelf, a middle section with a locking door mounted horizontally that opens 90-degrees to create a clever work surface that supports up to 100 lbs, and a bottom section that includes one fixed shelf below two columns of three adjustable shelves atop four cubby compartments with Gratnell trays [included] and an open center compartment. The two locking doors feature a total of eight adjustable shelves and eight fixed storage shelves with eight clear plastic trays [included], matte-finished steel cabinet pulls that match all other pieces in our Teachers Collection, and open on non-locking casters and continuous piano hinges that prevent fingers from getting pinched. Constructed in 3/4-inch hardrock maple melamine and thermofused edge-banding.
