Customer Reviews

Rated 3.0 out of 5 by 1 reviewer.
Rated 3.0 out of 5.0 by inexpensive vents I purchased four of these with the hopes of adding a little ventilation to the soffits of a shed I built. I was more ambitions than I should have been trying to get a round vent into a soffit. I should have either gotten a square vent or a 4” hole saw. Installation would have been much easier if I would have drilled the holes before hanging the soffit. Other than that, the vents have worked well to add ventilation to my shed. The fins of the vent are fairly flimsy but are easily bent back into place. I painted over these and they took the paint just fine. August 12, 2016
