Able to support up to 6.6 lb, the 3/8" ARRI-Style Anti-Rotation Adapter from Manfrotto is compatible with the 244 Mini and Micro Arms. It features a widely used connection in the video and cinema industries regularly found on camera housing rigs, monitors, LED lights, and tripods. The adapter has a knurled tightening knob, 3/8"-16 male threads, and two pins to prevent rotation. The adapter's plate is reversible to allow use without the pins.
