Size Chart - Louvered
Find your perfect fit by locating your opening's Width (W) across the top and Height (H) down the left side.
How to Measure: Measure your existing foundation opening width and height. Because these doors surface-mount over your opening (rather than fitting inside it), you can use a door that's larger than your actual opening. The 3" mounting flange simply overlaps and fastens to the foundation wall around your opening.
Measure your opening (the hole in your foundation wall). The door's mounting flange overlaps the foundation for a secure, weathertight seal.
Reading the chart: Model numbers indicate your opening size (H × W). Gray dimensions show total door size including the 3" mounting flange. Ranges indicate tolerance for surface-mount installation.
