The Pre-Rig Truss 3'9-1/2" section is a mobile lighting truss solution manufactured from aluminum 6082-T6 tubing. It features 2"x0.125" wall thickness for main tubes and 1"x0.125" for diagonals, with external dimensions of 30"x26". Each section includes 4 caster wheels for maneuverability and uses bolt connections. Designed to carry 2 internally-stored lighting bars with 3 Par 64 lanterns each, the system allows for quick deployment by lowering bars into operating position via guide rods and shank hooks. This configuration reduces transport space requirements while maintaining structural integrity for event lighting applications.
