The SHAPE 2-Axis Push-Button Arm with 3/8"-16 is 3.5" in length and features a 1/4"-20 screw on a padded platform on top and a 3/8"-16 screw on the bottom. It's designed to support a monitor or other accessory on your camera rig and to provide efficient push-button angle adjustment. Separate push buttons allow you to perform quick tilt and 360° rotation adjustments of your accessory. The push-button adjustment is achieved via built-in rosettes.
The top and bottom mounts each secure via an integrated D-ring that can be used tool-free, and there's also a screw head on each D-ring in case you want to use a screwdriver to tighten firmly.
