Durarail’s Park Rail gives deck builders the option of installing a continuous aluminum top rail up to 20 feet long. The rail’s plus-sized profile— 3 1/2 inches wide and 2 inches high—is designed to resemble the familiar dimensions of a 2×4 rail while offering the low maintenance and durability of powder-coated aluminum, according to Durarail. It’s available in nine standard colors and as many as 180 custom colors as well as 22 faux-wood-grain finishes. Park Rail Top Rail is manufactured by Excell Railing Systems Ltd. Durarail, duradek.com
