The Global Truss SQ-4110-.875 is a .875m (2.87') straight section of box truss made from high strength 6082-T6 aluminum alloy. The 6082 aluminum alloy is gaining in popularity over the 6061 alloy that is often used in truss fabrication because it has a higher tensile (10%-18% stronger) and higher corrosion resistance due to a lower copper content.
The coupler receivers, couplers and securing pins are all tapered which means a much tighter and stronger joint than you might find with other truss types. Additionally the couplers are solid pieces of machined aluminum and the coupler receivers are almost four times thicker than the rest of the truss for an extra measure of strength at a crucial point. This connection system also means quicker and easier connection than other on the market. Simply insert the coupler, push through the pin and secure it with the r-clip. No nuts, bolts or washers to lose and no need for special tools or wrenches.
