ABSTRACT:
A simplified assembly truss system rivets each power track inside one chord of each truss span so that the electrical components cannot be misaligned inside the chord during final assembly. The chord is slotted to receive lighting heads in its mid-sections, and short end slots allow interconnecting plugs to be inserted into matching power track ends. A stop captured by the rivets near each chord-end indexes the interconnecting plugs to ensure the final electrical assembly is correct.
