Featuring a ball head at each end, the SmallRig 5.5″ long Articulating Arm can be used to mount a monitor or accessory weighing up to 3.3 lb onto your camera rig at almost any angle. Compatible with a wide range of camera components such as a monitor, small lights, or sound gear, the aluminum and steel arm features 1/4″-20 screws on either end. Each screw mount features rubber padding to prevent your equipment from twisting and scratching. Both ball heads and the center joint are secured using a large locking lever, and each end features a tightening thumbscrew for easy accessory mounting.
