ABSTRACT:
A cornerless slip-on flange system for duct connections. The system utilizes flange pieces to form a frame at the end of a duct section without the use of connectors at the corners of the flanges, the frames of two sections being used to join the two ducts sections together. The flange pieces each have a male end and a female end with the male end of one flange piece being inserted into the female end of the adjacent flange piece at each corner to form the frame. The frames can then be installed on the ends of the ducts to be joined and fastened together by inserting suitable fasteners through preformed openings in the flange pieces.
