This precisely crafted articulating arm is designed for holding field monitors or accessories. The two 1/4"-20 threads at either end are attached to ball joints that rotate 360 degrees, plus a cut-out in the sleeve surrounding the ball allows the thread to be bent 90 degrees. The central elbow rotates 360 degrees for infinite adjustability. In addition to the included hot shoe adapter, a 3/8"-1/4" barrel adapter allows you to connect two things of different thread sizes.
