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.
Still unsure? Contact us with your opening measurements and we'll help you select the right size. Our surface-mount design accommodates slight variations in opening dimensions.
