4 5/8"W x 3 1/8"H x 96"L Straight Top Rail

The 5" system top rail measures 8 feet in length. It is precision molded and reinforced at the core with heavy-duty vinyl, which enriches the 5" balustrade with superior strength and structural integrity. The 5" top rail compliments all baluster styles within the system and becomes a versatile addition to porches, patios, balconies, decks, and more. The 5" system top rail is crafted in durable urethane, a molded polymer material that possesses a beneficial closed cell structure that locks moisture out. Urethane rails withstand moisture that can cause warping, splintering, peeling, staining, mildew and rotting.
