All curbs are constructed of high quality galvanized steel and many use the innovative tongue-and groove MicroLok design, which requires no tools and assembles much faster than the competition's product. Curbs typically include the wood nailer for roofing, gasketing to provide a seal to the HVAC unit, and duct supports and insulated deck pans, as required. Curbs are typically shipped knocked down but assembled curbs are available. |
