The TetherGear Tablet Holder from Manfrotto uses an adjustable sliding arm to support tablets that diagonally measure 9 to 13". The sliding arm and corner sections incorporate soft rubber grips that help secure and protect your tablet, while an included mounting adapter provides users with multiple attachment options to devices such as a friction arm, tripod, or tilt head. Supported mounts include 1/4" and 3/8" threaded holes, as well as Manfrotto and ARRI anti-rotation lugs and Arca-Swiss compatibility.
