The Atomos AtomX 13" Arm & Quick Release Baseplate includes a 10" 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. Both ends of the arm feature a 1/4"-20 male, and the baseplate attaches to one of these. 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.
