I wish to add one of those flexible/fabric collars around my main air
return duct in order to reduce noise and vibration transmission.
What's the proper term for one of those items? I'm trying to purchase
the parts to install this, but can't find any supplier on line.
Perhaps I'm just using the wrong search words.
