Duct Trim Ring

I need to run the 4 inch dryer exhaust line through a suspended ceiling tile. I would like to put a trim ring against the ceiling tile to clean up the opening. Do they make such a thing in 4 inch? I've found stove pipe trim rings, but nothing smaller than 6 inch.

As always, thanks for the help!

Search for 4" duct collar.

Dryer vents come with a 4" nylon washer type of collar but the duct collar is more like a coupling for solid pipe with a flange.
