Abstract: A duct stretcher (6) that is used to conveniently bring the joining ends of a sheet metal air carrying duct system together so that the two ends can be joined and essentially sealed. The tool (6) is configured such that the grip on the ends of the ducts is enhanced over that of a tool (6) having a single pivot point (22).
