Thank you for your interest in PetSafe® products. The information listed is an approximate measurement of the flap sizes. However, because flaps may shrink or expand overtime due to changes in temperature, we generally do not rely on flap measurements for replacement information. If you are not sure as to the brand of your pet door, you may wish to try and identify the brand first in order to ensure the correct replacement flap is purchased.
