Four-point truss forms the rectangular backbone of rigging setups where four chords carry the load rather than three, giving a wider, flatter profile suited to spanning larger structures and supporting heavier distributed loads. This category holds Prolyte S36R rectangular truss in lengths from 0,6 m to 3,0 m, plus a boxcorner section and a base plate for ground-supported builds, all finished in black for a uniform look on stage and studio rigs.
A pre-rig touring section (PRT 2,4 m, 8 ft, Euro) is included for productions that need faster, repeatable assembly with pre-fitted electrics or motor points. Subcategories group further 4-point ranges such as MD 52x52, FD44, FD34 and Slick GS profiles, covering both silver and black finishes for varied technical and aesthetic requirements across stage, studio, film and live event installations.
