Universal Ultra Arm v2

The Universal Ultra Arm is a strong articulating arm for attaching accessories to your camera or rig. It has two points of articulation so you can precisely position your device. It features interchangeable mounting screws, so you can attach it to either 1/4"-20 or 3/8"-16 mounting holes and mount 1/4"-20 and 3/8"-16 accessories to the arm. In addition, the included removable anti-twist divots allow you to securely lock this arm to compatible accessories to prevent it from twisting unexpectedly. Changing the mounting knobs is a simple task; simply depress the brass locking pin, allowing the knobs to be swapped out. The arm features two 25mm balls, providing the two points of articulation, and a locking lever that clamps the armature on the ball, holding the position you set.
