The Gravity Plate is a 1.7 pound (.77kg) 6.3" (160mm) machined steel disc with a high level of finish. It features Octa's recessed mount in the center for quick and easy connection. Perfect for a POS or an elegant and sturdy desk stand. The base is protected with a silicon ring pad. It is heavy enough to support the larger tablets such as the iPadPro 12.9" but light enought to pickup and move it around. The Gravity Plate is finished in matt black. Connect any of the Bridge components and your tablet will be at your finger tips.
