The 40-series truss is a larger version of the 30-series.
Generally this truss series can be used in similar situations as the 30-series, however, the loading and deflection characteristics are much better.
The main characteristics of the 40 series truss are strength, versatility, low unit weight and easy assembly.

The conical coupling system (CCS6) allows for fast, efficient and highly aesthetic assembly of permanent and temporary structures.
