The LIH-HOL2KNUC44 Double Knuckle Baluster is the most ornate in this series with Double Knuckles. Our Hollow Versatile Series Balusters are 1/2″ square by 44″ Tall. They have a round, doweled, top for easy installation into any of our wood handrails. As their name suggests they are extremely versatile and are often used with balusters in Wood, Twist and Basket and Scroll Series to create virtually unlimited design possibilities. These hollow versions are lighter weight, less expensive and easier to cut.
