Show Solutions 3' tall, 20.5" wide PRO Tower Truss with grade 8 bolts

A 3-foot section of Pro Tower Truss, 20.5 inches square, supplied with Grade-8 bolts. Tower truss is built for vertical loading rather than horizontal spanning, so this is the section used for ground-support legs, goalpost uprights, and line array towers. Three feet is the trim length: the piece added or dropped to set a tower to the exact height a venue ceiling allows, which is why most inventories carry several regardless of how many long sections they own.
