The ARKON Tripod Tablet Mount is a heavy-duty tablet holder that mounts on mini tripods and other supports with a 1/4'-20 mounting screw. It holds 7 to 18.4' tablets, including iPad Pro, Galaxy Note, and Surface Pro. Your tablet is easily inserted and removed by pushing down on the lower legs of the holder with one hand. Included with the holder are 10 support legs in different lengths. Choose the four legs that provide the best fit for your tablet. These insert at the top and bottom of the holder and can be easily adjusted in order to keep any side buttons and ports unobstructed.
