Product review (4 stars): Nice product
Looks like this will work just fine to replace the old vent. Well constructed. Would have given 5 stars, but not thrilled about the packaging that it was shipped in. Box was too small and vent was jammed in the box. It looks like it had to be forced closed. Instructions said that screws were included, but didn't see any. Original "Heartland" box was broken, so might have fallen out somewhere.
