The peaked cap installs with the 12" balustrade system newel post. The newel completes lengths of balustrade, and the peaked cap gives the newel a detailed appearance. Balustrade accessories help to define the balustrade with unique detail. Accessories can also compliment the home exterior. As with all balustrade components, the peaked post top is crafted with detail, precision and quality in rigid, high-density urethane, a versatile polymer material. Urethane possesses the classic beauty of material like stone or wood, but it is also moisture-resistant, light in weight and easy to work with. Urethane balustrade accessories will not peel, crack or decay and they are pre-primed.
