The Square Baluster is the traditional baluster and a popular choice. The crisp, simple design of the baluster creates uniformly textured lengths of balustrade. The Square Baluster has the look of a wood spindle, but it is molded in high-density polyurethane foam, a durable choice. Polyurethane spindles are impervious to damage caused by moisture, so they remain free of cracking and decay. Whether you are enriching a short stairway, an expansive verandah, or a backyard patio, we have an excellent balustrade system for your exterior. The Square Baluster is perfect for the traditional exterior.
