1:58 good comment about rotating the vent to face the house. Have heard that these rust pretty quick, so would be keen on your views as to how they're stacking up a year on (both as a the rust-proof finish and if it's made a difference in heating/cooling).
Good video, I believe the Aluminium type that you install doesn't rust compare to the metal ones, it's been a year since your post please confirm if any sign of rust.
@gurusevuppal758 sorry can’t recall, I have a ridiculous amount of screws & just used some of what I had. Recommend using a stud finder if worried about stud locations or old school knock method. Location wise I just roughly spaced them out evenly
