This solid and sturdy locking storage cubby system provides a central location to store backpacks and other valuables that need to be secured. One cabinet is a single horizontal row of four cubbies, and the cabinet includes discreet pre-drilled holes and fastening hardware that enable stacking more than one unit high. The doors are exterior mounted on strong soft-close hinges that prevent slamming on little fingers. All locks are keyed alike. Constructed in beautiful, durable 15mm birch plywood and 1/4-inch hard maple backboard.
