Prolyte H40R Rectangular Truss (aluminium, EN AW 6082 T6) designed for compact, high-stiffness builds with central loading for moving heads and LED/video displays. CCS6 conical coupling and three-sided webbing with thicker bottom braces reduce torsion from one-sided loading. Main chords are 48 × 3 mm; diagonals 20 × 2 mm. Custom lengths, including 71 cm, are available within the nominal 0.25–1.00 m range. Finish: user-specified as silver.
