Anyone know of a good deal on the 2 to 3 inch type circular flow rite snap in inserts? You know the ones that just take a hole saw cut out, then snap the insert in and there ya go... I know SLP sells them (see link below), but seems pretty pricey at $21 per insert. Gotta be a less expensive vendor out there, or can you find the materials at a hardware type store and just put em together. Looking to add some heat venting here and there. Thanks...

Try these?

Not sure if this will work for you ..they are small but you get 6 for 13.93 shipped to your door.

Thanks. I'll keep those in mind. Pretty sure I'm looking for 2 to 3 inch options, but I appreciate the idea
