The Mobile Tablet Storage Cart from Sandusky Lee offers secure storage space for up to 40 tablet computers. The steel frame features perforated panels for ventilation and locking doors on the front and rear with full-length piano hinges. An anti-skid mat and wire grommets on the top give you room for a projector, speakers or other equipment. The three interior shelves adjust in two-inch increments. Four swivel casters – two locking – let you easily move the cart between classrooms. Add a power strip charging system for an extra cost to turn the cart into a charging station. Choose from a variety of cart colors.
