Show Solutions 4" long, 18" x 12" box truss spacer. Bolt kit sold separately (FABRICATE TO ORDER)

A 4-inch spacer for the ST-1812 truss profile, a rectangular section measuring 18 by 12 inches. The rectangular shape puts extra depth in one axis, which is what long horizontal spans need, and a 4-inch spacer is the increment that dials a span in without redrawing the layout around it. Built to the same Pro Series standards as the full-length sections in the range. This item is fabricated to order rather than held in stock, so allow lead time. The bolt kit is sold separately.
