Ingenuity can be truly refreshing. Take our new concealed No Show Iron Baluster Fastener, for example. They’re designed to give you a clean, finished look without the need for adhesives or shoes. Simply slide the plastic insert into the bottom of the trimmed baluster, install the dowel screw into the tread, and screw the plastic insert and baluster tight against the tread surface. Made for all our ½" hollow square iron balusters, each includes tapered plastic insert, dowel screw, and instructions. For open tread and level run applications.
