ABSTRACT:
A duct connector frame having frame sections with a bottom wall, a front wall, a top wall and a rear wall. The rear wall extends downwardly at an angle to the front wall and forms a generally triangular opening in the frame section. A channel shaped pocket or support member is formed in the opening to receive and support the lower edge of a corner piece leg portion and the rear wall, adjacent the top wall, has an inturned portion that forms a stop within the opening for the upper rear surface of the corner piece leg portion. The support member and the stop maintain the corner piece leg portion in the opening in fixed abutting relation with the rear surface of the frame front wall.
