The Wooden Camera Inc. 279000 is a robust and versatile tool for photographers and videographers. The universal arm is designed to securely hold your camera or other devices at the perfect angle. This articulating arm is constructed from high-quality, durable materials, ensuring it can withstand the demands of frequent use. It 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 allows the user 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.
