Featuring a jaw clamp opening of 15 to 40mm, the SmallRig Super Clamp with Ball Head Arm can be attached to the crossbars of gimbals such as the DJI Ronin and FREEFLY MOVI Pro. The articulating ball head arm provides a 1 4 -20 mounting screw to support monitors, lights, and various other accessories weighing up to 3.3 lb. The short length of the arm allows you to keep your add-on accessory close. The super clamp can also be attached to 15mm rods on your camera cage or rig to support a monitor or other accessory.
