The F&V Lighting 4.2" Stainless Steel Articulating Arm allows for the mounting of LCD monitors or small LED lights to the top of your camera shoe mount. With a three-jointed arm, this accessory has a wide range of motion. A single-point lock knob allows you to easily secure the position of your arm in place. This articulating arm features stainless steel sockets that offer greater strength. This arm can be mounted either on top of a camera in a standard cold shoe via the cold shoe adapter that is included. The cold shoe adapter can also be removed revealing a 1/4"-20 male thread that can be used to thread the arm into 1/4"-20 thread-ins.
