The Kupo KG100711 Vision Arm with Removable Hot Shoe is a precision crafted articulating arm designed for holding field monitors or accessories. The two 1/4″-20 threads at either end are attached to ball joints that rotate 360°. Plus, a cut-out in the sleeve surrounding the ball allows the thread to be bent 90°. The central elbow rotates 360° for infinite adjustability. In addition, the 3/8" to 1/4" barrel adapter allows you to connect two accessories of different thread sizes.
