| #1 | Q: If my exterior vent opening is 27.25x13 inches (width x height) would the 27x13 be correct or do I need to adjust for exterior dimensions? A: I would do 27x13. There is a 1 inch flange all the way round to help cover. We can do the 1/4 inch but that does add a machine charge Asked on 2025-08-23 by Kristina |
|---|---|
| #2 | Q: Is there an option to have predrilled holes on the 4 edges for easy installation? A: Assuming you are asking about the flanges, Dayus does not offer predrilled holes. Since this is typically for outdoor use you do not want holes in the flanges as that might cause water penetration. Asked on 2025-07-23 by Reed |
