It was made to hang objects at a hook which is divided into both sides with a central point of 600mm of the arm as a standard, and there is a balancer and balance adjustment knob at the bottom and head parts to adjust balance. Also with an angle measurement board, it shows the slope. In order to prevent leaning of an arm, it is attached with a projection pin. Also it can be used while attached to a magnetic blackboard.
