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.
Interal produces a large range of corners, arches, and special constructions based on the Protruss 40/41 series.
The conical connection piece (same as for the 30/31) allows you to assemble your system in the shortest of time.
