This bottom rail is designed for use with the 5" Balustrade System. It is versatile in design and compliments all baluster styles within the 5" system. When you require a defining exterior element that offers more detail than a plain railing, the 5" Balustrade System offers enhanced style and durability. The 5' bottom rail is 8' in length. It is molded with precision in polyurethane, a high-density material with the feel of pinewood and the enduring qualities of a modern closed-cell polymer. The 5" bottom rail is impervious to damage caused by moisture and it does not attract insects. It is reinforced at the core with vinyl and pre-primed.
