System 35 Trio lighting truss. This build is for a floor area of 3.0m x 3.0m. The light gantry/truss shown has the following dimensions, 3.0x 3.0 x 2.5m high. A clever central box allows 1.5m radius arcs to be fitted to it via bolt on half conicals creating curving legs. This structure can be altered to other floor areas and heights by quotation.
