The Dual Head Cornermatic Classic automatically inserts and crimps specially designed transverse duct connector (TDC) and transverse duct flange (TDF) style corners in seconds. Lets you do a duct section, eight corners, in about 60 seconds with virtually no physical exertion. Compared to other methods of hand insertion and crimping, it’s a savings of 3 to 6 minutes per section of ductwork depending on size and gauge. The Adjustable Dual Head Cornermatic Classic adds the feature of automatically adjusting the upper crimping head to handle duct from 48" to 72" in length.
