Standard sheet-metal ductwork transitions illustrate maximum taper angles for airflow management in plan or side view. The details outline a fifteen-degree maximum typical angle for converging and diverging duct runs, alongside a thirty-degree maximum typical angle for inline equipment transitions. Unless indicated otherwise on plans, these maximum transition angles apply to all standard duct layouts.
