Also pay close attention to the profile of the selected pet door. You will have limited clearance
between the overhead door and the wall as it opens and closes. This clearance distance can vary based on how the door is installed as well as the type of door. Before ordering, visually check out this distance...if it appears that you have 3 inches or more as the overhead door opens and closes, then you should be fine with any of our recommended models below.
Important Note: Make sure you pay particular attention to the exterior dimensions of the pet door. It is this dimension that needs to fit within the dimensions of your lower garage door panel. Very often these sectional panels are 18-22 inches in height.
