You need a coupling that attaches to the main trunk and the round duct attaches to the coupling. Just make sure you get the right size coupling for the round duct. Where you buy the coupling, ask the sales person to show you how it attaches to the main duct and the size hole you have to cut. I would recommend that you seal the coupling with mastic after you attach it.
