The Triad-Orbit IO-LCK is a locking Hirth joint connection, boasting better stability and greater load support than ball joints, making it ideal for mounting microphones, displays, or speakers. Its IO quick-change coupler and support for 5/8"-27 and 3/8"-16 threaded devices let you expediently swap devices without having to unscrew anything. The IO connection rotates 360 degrees to allow easy and precise positioning.
