Protruss 40/41
The Protruss 40/41 series is the strongest and largest one in the mid-range truss. Just like the 30/31 series they have been designed specificly for professional light-and sound equipment, on exhibitions, for entertainment, theatre and discotheque environments. Thanks to its increased size, 39 X 39 cm, the loading capacity and maximum span are higher than the 30/31 series, which extends the possibilities by the extra margin that is so often required in large-scale projects.
