The Prova railing system from DOLLE offers interior and exterior railing systems that are component based, easy to install, and beautifully designed. The Prova railing system offers several different configurations that provide a sleek, contemporary, custom look at DIY pricing. Prova railings are perfect for any home - creating dramatic sightlines outside, and making small spaces seem larger inside. The Prova PA26a stainless-steel cable post adjustment terminals are designed to hold Prova 0.13-inch diameter cable infill in place on your 42-inch Prova posts. The PA26a cable post adjustment terminals are used only at the beginning and end of your cable runs; terminals are not needed on every Prova post in your system. Compatible with all Prova side mount and top mount posts. No special skills required - Prova is designed for easy assembly with basic hand tools.
