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.
A pipe coupler system for joining two coaxially aligned hollow pipe sections, wherein each hollow pipe section has an upper surface and a lower surface, comprising: a coupling tube having an outer surface conformable to an inner surface of said each hollow pipe section, wherein each end of the coupling tube is adapted to be slidably disposed within an open end of said each hollow pipe section; a first coupler clamp and a second coupler clamp, each of the coupler clamps having an inner surface with two outer parallel edges, wherein the inner surface of sa...
