The Atomos AtomX 13″ Arm & Quick Release Baseplate includes a 13″ ball joint articulating arm and a compact quick release baseplate that attaches to one end. It allows you to attach your Atomos monitor to your camera cage or rig via a quick release workflow. One end of the arm features a 3/8″-16 male for heavy-duty attachment to your cage or rig, and the other end has a 1/4″-20 male that the baseplate secures to. The baseplate includes a removable mounting plate with a 1/4″-20 mounting screw and rubber padding. The mounting plate is released at the press of a red button on the side of the baseplate.
