RH40SA is the flagship of rectangular section trusses for more complex projects: it was in fact developed for applications with heavy loads. Diagonals on all four sides prevent twisting. RH40SA represents the ideal solution for rental companies in the corporate / exhibition sector, it is equipped with an end plate connection system for greater resistance to torsion, which also limits its bending and deformations caused by impacts during the assembly / disassembly. These construction features guarantee absolute coupling compatibility with trusses of the same size over time. Lenght 400 cm.
