A corner for use in connecting flanges of duct sections includes two legs with a tab portion extending from each leg. The tab portion includes a portion that is co-planar with the surface of the corner allowing the corners to stack on each other without nesting. The corner is further configured so it can be utilized with both integral and non-integral flanges. Each leg of the corner has a stepped inner edge which at one portion is wide enough for use with an integral flange and at a distal end is narrow enough to be inserted into a non-integral flange.
