While cable lock and wire rope suspension systems are capable of hanging rectangular as well as spiral ductwork, it has not been as widely applied for that use. The invention of the KV Bracket for hanging rectangular ductwork is designed to change that. The patented KV Bracket, is an assembly of a Dyna-Tite Cable Lock with a specially designed duct attachment. This assembly allows the contractor to securely fasten the cable lock to the duct with sheet metal screws.
