Dave is correct, the Window Max is no longer manufactured. MaxxAir had them in their product lineup, and when the company was sold about 2 years ago, the new owners did not want to bother with this product and dropped it from the line.
We had them on 3 windows and wanted to buy another, and was lucky last year, when we found a couple still on dealer shelves. Now all windows have Window Max and when it rains, we can open windows to the edge of them for ventilation and even have security as window can be latched in the partial open position.
Google will find web sites still showing the product, but there are usually none available at those site, like these:
Window/Maxx Window Vent-00-455000 by MaxxAir - RV Part Accessories
Amazon.com: Maxxair 00-455000 Window/Maxx Louvered Vent: Automotive
But then again, this site shows they have them, but I doubt it. Usually they think it can be drop shipped, and soon we all learn it is not available again. But good luck....
Floyds RV, Window/Maxx Window Vent
Because we still want what seems to not be available, one could call it Internet-Teasing...
BTW, Bob & Sue, you have a good eye . . .
