Abstract:
1. A tool for installing a corner into a flanged channel of a sheet metal duct, comprising: a first jaw moveable relative to a second jaw between an open position and a closed position in a first direction, a third jaw moveable relative to the first and second jaw in the first direction, an actuator operatively connected with the jaws to move the first and second jaws between the open position and the closed position, thereby pressing the corner against the flanged channel of the sheet metal duct, and to move the third jaw against an outer rolled edge of the flanged channel of the sheet metal duct to crimp the outer rolled edge over the corner, wherein the actuator comprises an operating rod having cam surfaces, with the operating rod moveable toward and retracting from the jaws in a second direction substantially perpendicular to the first direction, wherein the second jaw includes a cam follower engageable with a first cam surface to move the first jaws from the open position to the closed position when the operating rod moves toward the jaw, and the third jaw includes a cam follower engageable with a second cam surface to move the third jaw against the outer rolled edge of the flanged channel of the sheet metal duct.
