Shown below are prices for typical duct opening sizes. We will give you a firm price quote at the time of order, but this chart will get you in the ballpark. If you have an oddball size to work with please call us. We will be able to do it and there won't be sticker shock, but we will need to consult. Call 509 535 5098. (pacific coast time)

Note: There is a 2.5 inch lip all the way around. For example, a cold air return designed for a 10 by 10 duct opening would have overall dimensions of 15 by 15. Short on space? Give us a call, we can probably work something out... go to home page
