Review: Felt Obligated to Leave this Review (Super Easy to Install) - And I'm happy to report that the installation of this dog door WAS A BREEZE. I don't understand why I saw so many reviews about how difficult this door was to install. It honestly could not have been easier, and my wife and I were able to install it in about 15-20 minutes. Not only were we able to install it very quickly, but we didn't use a drop of glue, nor did we have to use the zip ties that come in the package. Here's how we did it: 1. Separate all the pieces with a flathead screwdriver. Pull the two ball shaped pieces off of the frame of the door, they are meant to be removed. 2. Have someone hold up half of the frame against the screen in the location you're looking to install it. The second person should be on the other side of the screen with a box cutter. Use the box cutter to make tiny holes in the screen at all of the inserts on the frame that person 1 is holding. You should also make little holes for all of the pegs that are attached to the frame. 3. Grab the other half of the base, and snap it together through the little holes in the screen that you just made. That's it, frame is installed. No glue, no zip ties, and the hold seems to be pretty firm. 4. Take the box cutter, and cut the screen out of the inside of the frame. Take that piece of screen and snap into the inner frame piece that you haven't installed yet. Snap the inner-frame into the outer-frame to make the swinging door, and viola, you're done. 5. The little balls can be used to lock the door flap if needed. Again, this installation couldn't have been easier. The door works well, and has been handling the impact of my blind, 90 pound lab very well. If you're looking for an easy-to-install dog door, look no further.
Review: Miki loves her door! - Miki loves her door! We've lived in our house for almost three years. It has a nice sized deck with a corner arbor with a wisteria vine and we added a gate, two "sails" and a large umbrella so there is lots of shade. We thought our dog would enjoy being outside on the deck. For two summers she had no interest but this year we couldn't keep her inside. We ended up leaving the french door ajar with a 12" opening in the screen which not only let her in and out but multitudes of flies and mosquitos. We researched and ordered the Namsan screen door, installed it and OMGosh! Five practice runs with her and she has been in and out, in and out for two weeks now. Our HVAC blew last Monday night and was not replaced until Friday so we had to close the door and drop the blinds every afternoon because our den faces west and is typically 5~ warmer than the rest of the house so she learned to push through "her" door to then push the french door open too. (if we could just teach her to close the french door!). We thought initially that this looked flimsy and as others have mentioned, it is difficult to line up and secure the tabs but we used a rubber mallet and installed the zip ties and it is holding up. I think it helps that our screening is fiberglass and not metal so it has some flexibility. She's a little taller (about 17") at her shoulders but she just dips a little and has no problem and when the squirrels are in the arbor trying to eat the food from the bird feeders she flies through the door at top speed. It's holding up well! All in all we are thrilled with the freedom this gives our girl and with the overall quality.

## Features

- Auto-Closing Magnetic Door: Designed for cats, puppies, and all small pets to enter and exit without hassle. Equipped with a magnetic door flap that automatically shuts tightly right after your pet passes through. Dual side locks let you securely lock the door when needed (e.g., night time, unsupervised hours) for added safety.
- Ideal Size for Most Small to Medium Pets: Passage size: 8.3 x 10.3 inches; Outer frame size: 9.9 x 12.4 inches. Fits most cats, small to medium dogs. Pro tip: Always install based on your pet’s height (measure from floor to shoulder) to ensure optimal comfort and easy access, no more forcing or struggling.
- Durable Construction: Made of high-quality ABS plastic, this screen cat door is sturdy, scratch-resistant, and built to withstand daily use by active pets. Upgraded hardware, Larger screws and thickened hinges prevent deformation or breakage, enhancing overall durability and ensuring long service life.
- Install on Existing Screens: Directly install on any screen door, sliding screen door, window screen, or thin exterior door, no complicated modifications needed. For thick surfaces (e.g., aluminum doors, walls), use adhesive (glue) for embedded installation to ensure a secure, stable fit that won’t wobble.
- Installation Tips: The inner door flap does not include a mesh screen, simply cut and fit your existing screen into the flap for seamless integration. Recommended 2-person installation for efficiency and precision. If the flap sticks or moves unevenly, double-check the door frame orientation to ensure correct setup.

### ⭐⭐⭐⭐ 2 people is best!
*by C***I on March 23, 2024*

I was concerned about putting this together by myself and for sure it would have been much easier with 2 people. I was still able to install on my own, it just took probably 3X as long since I had to try and hold both sides in place while getting the screws in. I had to position one side then prop a heavy object against it order to keep the screw in place to the other side and get the nut on. The product is also very thin so it sits flush with the screen which was another concern since I was placing it on a screen with a sliding storm door. The storm door panel still slides fine without hitting the cat door. The product itself is a bit flimsy but so is my screen so I will have to see how well it holds up. For the price, it suits my needs so far. My one complaint is the door does not lock back into place at the bottom. If there is a magnet there, it is not strong at all. Once my cat goes in or out, the door stays ajar at the bottom which could allow bugs to get in.
