Abstract
A method of inserting a corner member into channel-shaped flanges of a duct. The corner member has first and second legs. The duct includes longitudinally extending duct panels. The channel-shaped flanges of the duct extend laterally from at least one end of the duct channels. The method comprises supporting the corner member, moving the duct toward the corner member into a position in which adjacent flanges of the duct are in registration with the legs of the corner member, and pressing the corner member into the duct flanges.
