Step 1 Determine Pet Door Location
- Measure and mark your pet’s shoulder height on the outside of the screen door with a felt tip marker.
- Determine the location for the pet door.
- Measure 2½" up from shoulder height line and draw a horizontal line using a level. This will be the position of the top edge of the pet door.

Step 2 Position the Template
- Remove the screen door by removing the door hinge pins or by removing screws that hold the door to the hinge.
- Place on a raised level surface such as a work bench or a board on saw horses.
- Place the marked side of door facing up.
Step 3 Cut the Opening
- Separate the Interior Frame from the Exterior Frame.
- Place the Interior Frame (with flap) on the underside of the screen door.
- Reference the mark made from the pets shoulder height (In step 1). Align the top edge of the Pet Screen Door Interior Frame with the line drawn 2½" above the shoulder height line.
- Use center groove on the Pet Screen Door for a metal screen and inner groove for a vinyl coated fiber screen.
- Mark the cutout with a felt tip marker. Using the frame as a guide carefully cut the screen using a utility knife.
Step 4 Install the Pet Door
- After cutting the opening in the screen, place the Exterior Frame on top of the Interior Frame.
- Use a rubber mallet and tap the two frames together until fully seated. Make sure you have a solid surface under the door to support it while the frames are assembled.
- Use a Phillips screwdriver to screw the two frames together using the six included flat-head screws.
- Place the screen door back on the hinges.

Exactly as I hoped
The screen door that was installed onto my window screen is perfect for my pet Rabbit. He loves going out to his run. He figured out how to work it with one push of his nose. No training necessary. I have only positive comments about it. It was a wish come true to be able to just open my window and there be a screen door on the window screen for him to just pop out of in the morning. And pop back inside for the night. Thank you!!
My cats love their freedom
Pro: My cats love the ability to come and go as they please. The door and the frame are well-made. We installed it a month ago and so far, the frame has stood the test of 2 cats coming in and going out multiple times a day. Con: Installation could be improved if the door hinge were part of the door, not part of the frame. Highly recommend this product.
Great product, easy to install.
Just installed the door for our small dog (5lbs) and is working very well so far. I was initially concerned because the door and frame are all plastic and I was concerned about durability. But for our small dog it actually made it better because the door is light and easy to push open. A heavier steel door would have been more difficult for a small dog to open. I found a great video on youtube on how to install, and it worked perfectly. Installation took 15min. Training took a little longer, but lots of treats and patience won the day. She is now going in/out of the door without assistance.
Possible to install without removing screen door.
I was concerned about the installatiion because I could not remove my screen door as it is between two sliding glass doors. However, it is quite easy to install the Petsafe door with the screen door in place. I put a small piece of wood, about an inch thick, on the bottom of the screen door frame and then set the inside frame of the Petsafe door on top of it. Using duct tape I stuck the inside frame to the inside of the screen door.. I marked and cut the screen from the outside then tapped both frames together from the outside with one hand on the inside for support. I didnt have a rubber mallet so I used gentle taps with my regular hammer, it doesnt take much. We are so pleased and kitten loves it.
Easy to install works great.
Bought this for our 13 year old rescued Yorkie. Her eye sight is not the best so finding the door was a bit of a challenge at first. We used some treats st first to entice her to use the door and now she uses it all the time. Very satisfied.
