Show Solutions 20.5" x 20.5" x 20.5" 6 WAY STEEL FLUSH BLOCKS with round tubes. Can be used with screw jacks

A six-way steel flush block for 20.5 by 20.5-inch truss, built with round tubes. Six faces let a single block serve as a corner, a T-junction, a cross, or the transition from a tower to a horizontal header, which cuts the number of specific fittings a shop has to stock. Steel rather than aluminum construction suits the heavier loads that 20.5-inch truss carries. The block can be used with screw jacks, so it also works as the base node of a tower needing height adjustment on uneven ground.
