ABSTRACT:
A compact handheld tool for installing corner pieces in ductwork is disclosed. The tool has V-shaped jaws that surround a duct corner. A corner piece to be installed on a flange of the duct is placed against a first of the jaws, and a second jaw closes against the a first jaw, pressing the corner piece against the flange. A third jaw engages with an edge of the flange and presses the edge over the corner piece. The tool can install a corner piece in a single operation independent of the orientation of the duct or tool.
