The 7" Tether Tools Rock Solid Articulating Arm can hold lights, monitors, viewfinders, mics and other accessories that can be mounted on 1/4" screws, and it connects to a camera to attach these accessories for use with the camera. A hot shoe adapter is included for connecting to a camera. The Arm can also hold tablets and smart-phones, per the addition of the appropriate Tether Tools accessory. To hold a smart-phone, you'll need to add a SmartClip Universal Mount. To hold a tablet, you'll need a combination of a Connect Lite and a Wallee Case for iPad & Galaxy (iPad and Galaxy are the only tablets supported). Many other Tether Tools accessories are available for different uses with the Arm. A notable one is a Mini ProClamp, which can attach the Arm to various round surfaces, like video rig rods, tripod legs, and stands.
A single knob loosens and tightens all the ball joints simultaneously. The screw at each end is a 1/4" screw. The Arm reaches a length of 7" when fully extended and supports a maximum of 4.5 lbs of weight.
