Spans up to 8’ are possible, allowing for more flexibility and few connection points to the building structure. Tate Duo also features a two-layer continuously threaded slot on the underside of the extrusion so that multiple threaded rod diameters may be use for hanging different equipment within a building. Replacing custom-built, on-site structural support systems, such as strut, with Duo offers the most flexible solution for future configuration changes of any pre-designed ceiling solution.
