All parts
Every listing says which openings it fits. Check your measurements on the part’s page, or start a plan and we’ll match parts for the whole house.
Find the vent for your opening
Enter the size of the hole in the wall. We check it against every vent’s documented range, the same rule your plan uses.
Your opening
Foundation and eave vents, or the duct size for a dryer.
How to measure
A tape measure and two minutes per vent.
- Take the old vent off, or measure inside its frame.
- Measure the hole edge to edge, across and then up. Not the face or flange.
- Write fractions as 15 1/2. Count how many vents share that size.
