SkeleCore™ is an in-duct cylindrical tensioning device (CTD) that eliminates sagging and wrinkling. It maintains an inflated appearance, even during idle air handler periods, and eliminates the popping sound associated with equipment start-up. End caps also have a taut, flatter appearance. The CTD consists of a 3/4-inch-diameter, lightweight aluminum tube supporting a series of 3/16-inch-diameter powder-coated steel, 360-degree connecting rings, which are precisely sized to administer tension on the inner fabric duct walls for a permanently inflated, streamlined appearance. Its backbone tubes are 6 feet long and designed to easily snap into the support rings and couplers with a spring-loaded, quick-connect/release mechanism. SkeleCore is available in 15 diameters ranging from 8 to 36 inches. According to the company, it is compatible with all cylindrical fabric duct track or cable suspension systems, and is a retrofit replacement for all other fabric duct brands.
