Mount these workstations on a flat vertical surface to create a steady horizontal surface for writing, typing, or tinkering. They work as a case when closed, with a 2 _3/4"-deep interior for carrying a laptop, small tools, and other supplies. When you need a workstation, mount them to a metal surface such as an electrical cabinet with the included magnets, or a nonmetal surface such as a wall with the included suction cups. The magnets and suction cups screw into either exterior side of workstations; leave magnets on one side and suction cups on the other to be ready for quick use. On the interior, workstations have a movable rubber work surface, magnetic strips across the top for holding tools, and wire rope cables to keep workstations open at a 90° angle.
