The 12″ polyurethane balustrade System is Worthington’s largest railing system. This particular balustrade system is ideal for roof tops on commercial buildings and/or commercial balconies where the balustrade will be farther away from a normal eye’s view. This system contains two heavy duty PVC pipes for the inserts of the top and bottom rails. It is available from 4′-10′ lengths and the newel posts are available in a plain or raised panel. Due to the size of this balustrade system, the railings are only available in straight sections. The Worthington 12″ polyurethane balustrade system is structural and is BOCA and ICC building code compliant.
