A pole mounting device has a rod with a ball at one end and a clamp at the opposite end, and a holder tube with a ball socket that forms a ball joint with the ball on the end of the rod. The holder tube rotates relative to the rod about two transverse axes. A pole is held in one end of the tube and a set screw in the other end adjusts rotational resistance of the ball joint. The mounting device can mount flag poles, and with an adapter, mobile electronic devices or other articles.
