Decide where on your door to install the pet door.

  • The pet door does not have to be installed in the center of your door. You may choose to adjust it to the left or right.
  • If you are installing it in a paneled door, align it within a panel for ease of installation.

Use a level to draw a vertical line for the pet door to be centered on. If you are placing the pet door centered on your door, measure to find the center and draw a vertical line for the center of your door.
