Product Overview

The Prova railing system is a component based, easy to install, interior and exterior railing system. The Prova system offers several different configurations that offer a sleek, contemporary, custom look at DIY pricing. The Prova PA1 top mount aluminum post with brushed aluminum finish provides a minimum 36 in high railing with 8 levels of infill. Infill spacing is under 4 in which makes this post IRC code compliant. There are no special tools or skills required for the installation.

I love this product. It provides easy installation and sleek modern look to your home or business. It truly is remarkable technology. I wish it was easier to buy in store and not so pricey. But if it was more affordable then it would not be so appealing. thank you
