FS45 Truss is based on the FS44P- 400mm * 400mm truss design and is used for applications such as LED screens where balanced centre rigging of the screen panels on the truss is essential. A central chord with ladder-style horizontal bracing on the bottom face of the truss allows LED panels to be clamped directly onto the centre chord. The ladder-style horizontal braces creates more and more clear hanging space along the chord compared to the outside chords.
