摘要： A flange to be assembled to a duct member includes a plurality of pre-fabricated apertures or areas of weakened wall strength for receiving fasteners to assemble the flange to the end of a duct member. The apertures may be spaced apart such that the fasteners can be inserted at regular intervals along the length of the flange and the length of the end of the duct member.
