We suggest that when pre-cutting the rough for any pet door, that you add at least an 1/8" to the width and height to allow for easy fitting. Some Rough cuts are more precise and may fit tighter if the hole is not completely true.We always recommend that the door is on hand prior to cutting. We will not be responsible for re-fitting after the fact.
