OT: Where to buy HVAC duct parts?

[Foogoo]

Is there anywhere local where I can get a 15" circular HVAC outlet cover or cap?

what kind of cap do you want like a roof cap or to just cap off a duct?

Your best be would be just goto a local HVAC supplier look in your phone book

Just capping off a duct. I'll check the phone book, I also might just fabricate one with sheet metal...

 

[frontman21]

unless you have some sheet metal at your house already it will probably be cheaper to buy the cap.

Man I didn't know I'd have this much trouble...

I checked the yellow pages, yahoo and google and all I could find were HVAC contractors or manufacturers. Does anyone know of a place that would carry such a part that would sell to the public (local preferred, but online ok)?
