The ST76R is a large, heavy-duty fork and pin truss series. Its revolutionary design delivers all of the advantages of Thomas SuperTruss in a 76 x 52cm (30" x 20.5") layout. Extended spans and super heavy loads required by the entertainment industry are covered by the ST76R. The SuperTruss 76R series provides a substantial increase in load bearing caapacity compare to our GP Heavy Duty truss. Castor wheels come as standard equipment.
