This is the toughest tablet holder you will ever see. This sturdy tablet holder features 1/4 and 3/8 threaded mounting points on all sides, allowing it to be mounted from either side or for peripherals to be placed around it. The clamp has a spring-loaded jaw that allows the tablet to be easily placed and removed with one hand, with or without a protective case. The adjustment knob can be tightened for added security when the tablet is used in vibrating situations, such as in a car. The clamp is covered with a non-slip protective rubber that keeps it secure.
