1½″ ductboard. AmCraft Red 1084 / Blue 1087. Tape, square, straightedge and duct knife; reducers also use the level-and-trim method.

The app checks whether the requested fitting fits the supported board and tool paths before showing marks. Some sizes and short, steep reducers are not supported. 2″ board and one-piece transitions are not currently supported. Tin Badger does not size ductwork for airflow.
