Existing Pet Door Opening
RetrofitFor retrofit installations, if your home already has a pet door installed in a wall or door, upgrading to Pawport is quick and easy. Choose a Pawport size that is slightly larger than your existing pet door opening, and Pawport will easily adjust to fit. Measure only the actual opening in your door or wall, not the entire outside edge to outside edge of your pet door frame. Existing openings must measure no larger than 13.25” W × 24.25” H in order for Pawport to be able to retrofit over it.
| Size | Opening Requirements |
|---|---|
| M | Less than or equal to 13.25" W x 16.25" H |
| L | Less than or equal to 13.25" W x 20.25" H |
| XL | Less than or equal to 13.25" W x 24.25" H |
