The Crab-Shaped Clamp & Magic Arm with Cold Shoe from SmallRig consists of a crab-shaped clamp and a 11" magic arm. It is made of aluminum alloy and stainless steel to increase robustness and durability. The clamp features 1/4"-20 and 3/8"-16 threads and a clamping range of 0.6 to 2.1". The magic arm has a 1/4"-20 screw at one end and a cold shoe at the other, allowing it to be mounted onto such accessories as a cage, LED light, microphone, and monitor. The magic arm together with the clamp quickly connects cameras, monitors, lights, and other equipment with pipe posts, tables, bike bars, and more. Both the clamp and the magic arm are fitted with rubber pads to prevent scratches and help lock equipment in place.
