The H40R Rectangular Truss is a rectangular standard H40 truss constructed of main chords (48 x 3 mm) and diagonal members (20 x 2 mm). It features the CCS6 conical coupling system and has three-sided webbing with thicker braces on the bottom side for easy mounting of moving heads and central loading, reducing torsion effect from one-sided loading. The truss measures 387 mm high by 287 mm wide. The spigot orientation follows that of the S series truss, allowing easy assembly while still on the floor. The self-weight of the truss is already included in the loading figures.
