Single and Double Branches taper as the new line enters the mainline. This is because the new line is bringing in more air. The exit part of the branch (toward the fan) is bigger to accommodate the increase in air. The new line typically enters at 30 or 45 degrees so as to 'merge' into the airflow.

  • All branches are 18 gauge or heavier
  • Standard at 45°. Available in other degrees.
