DuctSox has added the SkeleCore Pull-Tight to its line of fabric duct products. The SkeleCore Pull-Tight is a fabric Retention and suspension system that uses a combination of internal hoops and tensioning baskets in order to maintain the shape and retention of fabric duct. According to the company, the Pull-Tight is suspended from either a Tension Cable or Track Suspension System and is tensioned "externally" using a Tension Cable (or Track) Lock. The company claims its Pull-Tight improves start-up performance and aesthetics when compared to multiple row, horizontal suspension systems.
