That lip won't keep out more than a drop of rain. It is there to allow the install of a bug shield, which hangs on the lip and is secured by a spring. The difference in length is probably to allow it to fit in the new furnace and not the old one. Chuck
Perhaps I should install the old one.
The old one functionally has a "lip" as well to keep water runoff from being ingested. I think the full width lip on the new one does a better job of it though, compared to the beveled circular lip on the older style.
