Abstract
A staging system has a hand rail coupler system with an inner coupling tube which interconnects two coaxially aligned hand rail sections. A pair of opposed coupler clamps are aligned over the interconnected hand rail sections. A studded knob extends through the opposing coupler clamps and the inner coupling tube and is connected to a nut. Rotation of the studded knob acts to tighten the coupler clamps to hold the hand rail sections in place.
