F31 – 2" Single Tube Truss

The versatile and expandable F31 truss comes in a wide range of sizes, so it can be used to make square or rectangular frames of any length or diameter. The F31 truss can even be used for freestanding signs when anchored with a sturdy Tube Base Plate.

Connecting F31 segments together to form the desired size and shape is easy, because each piece of Single Tube Truss comes with attached conical connectors, which incorporate the Cosmic Truss famous conical coupling system. This unique connector, developed from “mouse-key” technology used in oil rig structures, helps to maintain overall rigidity, particularly at key stress points. Conical coupling is also quick and easy to assemble, and because it is genderless, each piece has even greater versatility, offering more rigging options.

Although extremely lightweight, F31 truss is also very rugged and durable. That’s because its made of the same high-strength 6082-T6 extruded aluminum alloy as as our other trussing products, a material so strong, rigid and corrosion-resistant that it is used by the aviation industry for aircraft construction.
