Part of the Super Knuckle system that features a sleeve that tightens and holds a ball accessory at each end, the Ball Head with 1/4''-20 Quick Release Bracket for Monitor from Kupo moves omni-directionally in the optional sleeve and connects to monitors via its 1/4"-20 quick release bracket, making it perfect for temporary installations. Adding an optional ball at the other end of the sleeve creates a mount with flexible positioning.
