How It Is Used
Fixed to the stand rod, the boss head holds a clamp at the height and angle needed for condensers, flasks or sensors. Seat the rod firmly in the V groove so the clamp cannot turn or slide, tighten the thumb-screws firmly by hand, and face the open side upwards or towards the stand so the rod stays in the groove if a screw loosens.
