Onyx is the new matte black Stainless Steel Rod railing from Viewrail. Onyx Rod Railing has the same sleek profile as cable railing but is stronger, more durable and able to be bent to turn a radius. Because it’s rigid, it’s much faster and easier to install than cable. Each rod is 1/4-inch in diameter and is not prone to sagging or deforming. Made of powder-coated 2205 stainless steel, Onyx railing delivers incredible strength from a slim profile and provides real protection while maximizing the view through the railing. It’s designed for both residential and commercial applications.
