ABSTRACT:
An apparatus for inserting the legs of an L-shaped corner member into corresponding channels of elongated flange members used in an assembly for connecting the adjacent ends of sheet metal ducts. The apparatus, in a preferred form, comprises a base member that is adapted to receive a first flange member in a receiving position. A first corner positioning member is attached to the base member and is adapted to position a leg of an L-shaped corner member in confronting relationship with the channel of a first flange member. First insertion apparatus is attached to the positioning member for selectively inserting the positioned leg into the channel of the first flange member a predetermined distance. A second corner positioning member is attached to the base member for orienting an end of a second flange member in confronting relationship with respect to the other leg of the L-shaped corner member. Second insertion apparatus is attached to the base member for forcing the second flange member onto the other leg of the L-shaped corner member a second predetermined distance.
