SkeleCore by DuctSox is a fabric clamp-together duct (CTD).
SkeleCore by DuctSox is the first fabric clamp-together duct (CTD) that 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. Competing products and manufacturers either use special external hangers or non-tension, in-duct 180- or 360-degree rings, which still show partial deflation. The "deflation-buster" SkeleCore consists of a 3/4-in. diameter, lightweight aluminum tube supporting a series of 3/16-in. diameter powder-coated steel, 360-deg connecting rings, which are precisely sized to administer tension on the inner fabric duct walls for a permanently inflated, streamlined appearance. SkeleCore’s backbone tubes are 6 ft 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 in.
