The Kupo KS-312B Tethermate table for MacBook 15 inch and 16 Inch is a portable aluminium plate that provides a simple and portable solution for shooting direct to your laptop on location. Featuring both 1/4"-20 and 3/8"-16 female threads on its underside the Kupo Tethermate can be mounted directly on a tripod or any light stand that comes with 1/4"-20 and 3/8"-16 male threads. The difference between the previous Tethermate KS-300B and this KS-312B Tethermate is the inclusion of three mounting slots under the platform. These accessory mount slots make it fast and easy to connect additional accessories with the U-shaped sliding plate, including mouse table, hard drive storage tray and cup holder!
