RectorSeal has added 3- and 6-inch diameter Dura G-O-N models to its Glue-On-Nozzle product line of decorative downspouts for commercial building roof drains. Dura G-O-N is a high-impact polymer version of the original nickel-bronze G-O-N and offers the same easy, cost-saving installation features. Dura G-O-N and the original G-O-N are decorative downspout nozzles with a theft-resistant glue-on design that can be installed after the wall or building is completed. All of the models feature the integration of an aesthetic patina-like bronze color during the polymer injection molding process, which makes its simulated oil-rubbed finish indistinguishable from a metal downspout. The Dura G-O-N is for retrofits, less-visible back-of-building applications, or smaller projects with only a few roof drains. 713-263-8001; www.rectorseal.com.
