I will try and get some at the weekend. I think Jeff has some photos of his and mine is similar.
Basically its 2x 2m lengths of 2" square plastic trunking (from B&Q) with IEC & DMX sockets fitted every 12 inches. They link in the middle with Powercon connectors and DMX patch leads.
These then fit inside the tri-truss with a powercon connector and power lead for mains and a dmx socket and lead for the dmx.
Lights are hung and very short iec leads and dmx patch leads are used to connect the lights.
