The 11in rock’s arm is a precise and versatile articulating arm that will support up to 17.6lbs and is designed for holding field monitors, recorders, led lights and microphones on camera rigs. The friction wheel controls ball-joint tension simultaneously, making the arm handy and convenient to operate. The ends are engineered for 360 degree rotation plus 90 degree pivoting that provides great versatility for easy positioning. One end features a 1/4"-20 male stainless steel accessory tip, and the other end a 3/8"-16 male stainless steel accessory tip. A unique taper engagement mechanism facilitates fine ball-joint adjustment even when tightened. This provides a great solution for different connection and mounting needs in video and film.
