The Zonitor ENG Large mount kit allows you to quick-release a monitor from a Zamerican articulating arm and the arm from the top of your camera. This kit allows you to mount any device with a ¼ 20” (or 3/8 16”with ¼ 20” to 3/8 16” adapter) screw hole, such as an external on-board monitor, lights, and/or hard drives, using a Zamerican Arm. The arm is mounted on a Zicro Micro that is attached to your camera's handle. The Zicro Micro prevents unwinding with the use of the L prongs.
