When you require more detail and character than a standard railing has to offer, the 5" Balustrade System offers the elegant styling and minimal prominence that you seek. The 12' bottom rail is a finely crafted and durable addition to the 5" Balustrade System. It features crisp lines that compliment the baluster style of your choice. The 5" system bottom rail has the character of wood, but it is crafted in precision molded polyurethane, a rigid foam that offers traditional detail and the moisture resistant qualities of a modern closed cell polymer material. The 5" bottom rail is pre-primed and reinforced at the core with heavy-duty vinyl piping.
