ABSTRACT:
A hand-held power tool for installing the corners of transverse duct systems. The tool has powered jaws that, when placed over a standard corner piece and one of the flanges of the duct, will first clamp the corner piece in place on the flange and then crimp the flange over the corner piece to complete the installation. Both operations of clamping and crimping are accomplished with a single stroke of the operating rod of an air cylinder.
