A/C duct vent cover removal

[starnes550]

I have a 2016 Rockwood 2604 WS. How do I remove the A/C duct vent covers. I'm wanting to check and make sure they are connected properly, but can't seem to figure out how they pop off. I don't want to break them. Thanks!

Take a small flat screwdriver or butter knife and wedge it in the gap between the base and register (part that swivels) and it'll pop off.
