It is perfect for this use and fit without modification

I am using it to vent the refrigerator on my Airstream Interstate Touring Coach. It is perfect for this use and fit without modification. Very well made and attractive.

Good vent replacement -but- NOT THE PRODUCT PICTURED

This was a perfectly sized replacement for my 21 foot 1990 Sea Ray Mercruiser inboard. The mounting holes were slightly farther apart so I ended up having to drill two new holes on one side and reuse the old holes on the other side for the mounting screws.BUTthis product is NOT the one pictured! The part number given in the description references a product that comes in three colors: black/chrome all back and all white. The photo shows the black/chrome version but the description just says "white". Not knowing which one to believe I ordered a pair and hoped for the black/chrome as pictured - but alas it was the all white version.The product itself will work great but my major complaint is the lack of proper description matching a photo of the product.I have attached a real photo of the product
