I’ve been on the hunt for a truss solution that could be easily reconfigured for different applications. It turns out the options are not immediately apparent, but with a little searching there are some gems. Here are the results of my research thus far:

• UltraBeam
• Unistrut
• 80/20
• Kee Klamps
• SpeedRail
• Global Truss
• Truss Works
• Octanorm
• There are a number of Chinese solutions for modular aluminum. Meike, Al Fang, Ouyu

Thanks to Troy, Richard and Eric for suggestions.
