The LIH-HOL15044 Double Knuckle Baluster has two Knuckles with Spoons above and below each Knuckle. Our Gothic Series balusters are 9/16″ square by 44″ tall. They are Hollow iron with a hammered detail and a round, doweled top, for easy installation into our wood handrails. The hammered detail of these balusters create a more bold and detailed look than the plain square alternatives. While our Gothic Series works especially well in homes incorporating a European feel, it is a very versatile and used in a wide range of styles and designs. These hollow versions are lighter weight, less expensive and easier to cut.
