    摘要: Substantially scrapless methods for fabricating angled ductwork fittings. The methods include cutting a pre-determined pattern into a blank comprised of sheet metal material to separate the blank into two or more portions. Bending each of the portions of the blank so that each portion forms a rectangular section of ductwork pipe and joining the sections of ductwork pipe together to form an angled fitting. A transition fitting comprising a transition plate including a first panel and a second panel. The first panel is sized and shaped to be positioned in and to blank-off a gap between a first pipe and a second pipe. The second panel is positionable within the first pipe to direct fluid traveling through the first pipe into the second pipe.
