S40 mast sections are constructed of main tubes (50 x 4 mm) and diagonals (25 x 3 mm). Equipped with the CCS6 conical coupling system, the S40 is fast and easy to assemble. Due to its 3-sided webbing the S40 truss can absorb vertical as well as horizontal loads, which make sit ideal for outdoor or 3 dimensional structures. The one-sided horizontal bracing facilitates safe and easy access of the mast sections when in position.
