The Ball Joint connects to any STEM component with internal threads by way of its externally threaded end pieces. Attached to the externally threaded pieces are brass balls located inside the Ball Joint component. One brass ball and threaded end allows for rotation through 360 degrees. The second ball and threaded end allow for 360 degrees of rotation as well as 90 degress of articulation. After a desired position is found both ends are locked by the tightening of a single bolt (5/32" Allen Key). When this bolt is tightened a wedge mechanism inside the Ball Joint exterts a force on two caps which are then pressed against the balls which holds them firmly in place.

By nature of the Ball Joint design the tightened position is more than adequate for regular pressure being applied against it (switch use) but under extreme pressure the Ball Joint will move but still maintain the same rigidity (i.e. Moving the locked Ball Joints will not cause them to loosen). Locked Ball Joints may still be moved without any damage to the ball and internal components of the Ball Joints. The tension on the Ball Joint is adjustable meaning that the tighter the Ball Joint is locked the more force that is required to move it.
