Featuring a ball head at each end, the 5.5" long Ball Head Clamp with 3/8"-16 ARRI Accessory and 1/4"-20 Screw Mounts from SmallRig can be used to mount an accessory on your camera rig at almost any angle. The clamp can support loads up to 11 lb, and the ball head ends are interchangeable.

Compatible with a wide range of camera components such as a monitor, small lights, or sound gear, the aluminum arm secures both ball heads with a center locking thumb lever, and they allow 360° rotation. One end of the arm features a 1/4"-20 screw, and the other end features a 3/8"-16 screw with ARRI accessory anti-twist pins. Both mounting screws tighten with thumbscrews for easy accessory mounting and unmounting. An Allen wrench is included for additional torque when tightening the thumbscrews.
