For many classrooms, their device security system is simply locking the door at the end of the day. This new mid-range, top loading model is ideal for these environments and at a lower cost than our premium models. It has all the features of the premium models, including a padlock for securing the devices inside. The only difference is there is no locking block and pin to secure the tub to surfaces. Tech Tub® Standard has the capability to charge up to 6 Chromebooks?, iPads® or other tablets. It makes sharing small sets of devices easy within a classroom or throughout a school. Adjustable dividers can accommodate most cases and the side cable channel helps keep cords neat, tidy and lined up with each device.
