Trolleys are designed for devices on the move! They store up to 12 iPads, depending on the iPad case. The adjustable handle and built-in casters ensure that students from grade three and up can take part in managing their devices. The Tech Tubs® can also be placed around the classroom to reduce deployment bottlenecks. These Tech Tubs can clip and move together like a 10-device tub or can be two separate 6 device Tech Tubs to keep them separate (only the top tub is removeable).
