This 8" Universal Ultra Arm from Wooden Camera is a strong articulating arm for attaching accessories to your camera or rig. It has four points of articulation so you can precisely position your device, and a center arm that features nine 1/4"-20 and eight 3/8"-16 threaded mounting holes for additional accessory mounting.

The Ultra Arm features interchangeable mounting screws, so you can attach it to either 1/4"-20 or 3/8"-16 mounting surfaces and mount 1/4"-20 and 3/8"-16 accessories on the arm. In addition, 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 four 25mm balls, providing the four-points of articulation, and two locking levers that clamp the armature on the ball, holding the position you set.
