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 said each coupler clamp is generally conformable to an outer surface of said each hollow pipe section, and wherein said each coupler clamp is adapted to be disposed in opposing relationship on the outer surfaces of the hollow pipe sections, the first coupler clamp is adapted to be disposed on the upper surfaces of the hollow pipe sections and the second coupler clamp is adapted to be disposed on the lower surfaces of the hollow pipe sections, so that the inner surface of said each coupler clamp contacts a portion of the outer surface of said each hollow pipe section and the outer parallel edges of said each coupler clamp are parallel to a longitudinal axis of said each hollow pipe section; and a threaded fastener and a nut for releasably securing the coupler clamps on the hollow pipe sections, and wherein the coupling tube includes a hole extending through opposing walls of the coupling tube, the hole being sized to accommodate passage of the threaded fastener, and wherein said each coupler clamp has a hole sized to accommodate passage of the threaded fastener, so that the threaded fastener is insertable through the first coupler clamp, the coupling tube, and the second coupler clamp so that tightening of the threaded fastener in the nut causes the first and second coupler clamps to secure the hollow pipe sections together.
