Questions

Does it come with a cover to lock it?

It does come with a cover that slides in on the inside.

Will this keep one pet in while letting another out?

This is not an electronic door so any pets will be able to go in and out if they push hard enough. In addition, it will not prevent any stray and other animals like raccoons from getting in.

How do I know what size is best for my dog?

When installing the Endura Flap wall door you want it to clear the top of your dog's back by 1-2 inches, minimum. You also want the step over to be comfortable. Lastly you want the width to allow your pet to go through without touching the sides. Here's a measurement guide with tips on how to determine the correct size.

Product Details

The Liberty Wall-Mount Dog Door is designed for homeowners who want a true wall solution not a temporary modification. It creates a finished passage through exterior walls while helping preserve the comfort of your home. Security is paramount and the solid aluminum frame and interior locking cover give you control when you need it.

The clear flexible flap is intentionally lightweight so smaller or timid pets can use it comfortably. At the same time it is strong enough to handle daily traffic in busy households. The magnetic sealing system adjusts as temperatures shift which helps maintain a consistent close even as materials expand or contract. In real life this means fewer drafts and a more secure seal throughout the year.

If you live in a colder climate or simply want added insulation the double flap option provides another layer of protection. Flaps are replaceable which protects your long term investment and keeps the door performing well over time.

Installation is designed for walls between 2 and 7¾ inches thick and includes a built in tunnel system that bridges the interior and exterior cleanly. For step by step guidance see the Installation Guide. If you are unsure about sizing you can review our Measurement Guide before selecting your flap height.

Here's a measurement guide with tips on how to determine the correct size.
Is the Endura Flap large wall mount door large enough for a lab? Due to variations in individual pet sizes within a breed, we generally prefer to go by height and width instead of breed. You can visit this page on our website to learn how to measure for a pet door.
Is the flap on the interior or exterior frame for single flap model? For the single flap wall mount, the flap is attached to the interior frame. If you live in a very cold climate, we'd recommend the double flap model to keep snow out of the pet door tunnel.
What side does the locking cover slide in? All locking covers slide in from the top. If you purchase a double flap model, the locking cover can be used on the inside or outside frame. If you purchase a single flap, the locking cover is on the interior frame (the side closest to the inside of your home).
How high off the floor should my dog door be? Generally, every pet door should at least 3" off the floor to maintain your door or wall's integrity. The distance between the bottom edge of your pet door and the floor is called the step-over, and is an important aspect of determining how big of a pet door your dog requires. The step-over should be easy for your dog to "step-over," and never be more than a third of your dog's height. You can read more about step-overs in our measuring guide: /pages/measure-your-pet.
How easy is it to clean the flap? It is extremely easy to clean the flap. All you need to do is wipe it down with warm water and mild dish soap. Do not use any abrasive cleaners as you may damage the material.
I don't want my cat to get outside, is this cat proof? A manual pet door is pretty easy for smaller pets to use, even in the larger flap sizes.

Are replacement flaps available? Yes, we carry Liberty Pet Door Replacement Flap. They will work for all Liberty Pet Door models (wall mounts, doggy door mounts, window sashes, and sliding glass door patio pet doors).
Are the panels/flaps flexible? Seems like it would trap a dog if it backed up. The Liberty Pet Door flaps are comfortably flexible and suited for a wide variety of pets. Your cat or dog should have no problem backing up and won't run a risk of getting pinched.
I do not have to contend with wind or rain. If I buy the single flap version of the wall dog door is it possible to add the second flap in the future? It is possible. Please reach out to Customer Service to order an exterior frame and flap. Note, you cannot change an Liberty Pet Door Mount to a Wall Mount.
I want to get the large pet door for my dog, but I am concerned about a person fitting through an x-large door. All Liberty Pet Doors come with a locking cover. This cover can be used to keep your pet inside by blocking access to the doggie door. It also can be used to keep intruders from entering your home. It is made from a special polymer that is as strong as 1/16" sheet of steel. If you need to, you can purchase an additional Liberty Pet Door Locking Cover. We also have a product called the Watchdog Steel Security Pet Door Cover that provides maximum security for any pet door, complete with a combination lock. The cover comes in sizes large enough to fit even the XL dog doors for wall mount. Security consultants agree that dogs are a good burglar deterrent, especially one that barks. If you want to leave your pet door open make sure the gate to access your yard is locked and you post a “Beware of Dog” sign.
Is the Liberty Pet Door for Walls easy to install? Ease of installation is very subjective, and it depends on skill set or access to certain tools that might be needed. The installation of a pet door into a door is easier than installing it through a wall; however installing it into a door is more complicated than putting a pet door into a sliding door track. We recommend a contractor for installations that involve cutting into drywall.
How secure is the locking cover on the Liberty Pet Door? The Liberty Pet Door features a secure locking cover made of high-strength material comparable to 1/16" steel. Its integrated locking latch ensures the cover cannot be lifted or tampered with from the outside, providing a robust barrier for your home.
Can the Liberty Pet Door be customized for pets with limited mobility? For pets with limited mobility, we recommend sticking to the single flap model and installing the pet door as low to the ground as possible. If your pet is having difficulties opening the flap, you can put tape on the magnets to make them less strong.
Can the Liberty Pet Door handle extreme temperatures, both hot and cold? The Liberty pet door can withstand temperatures between 0 and 100 degrees. For an extreme weather pet door, we would recommend checking out the Endura Flap pet door.
How does the flap design ensure ease of use for timid pets? Unlike other high quality pet doors, the flap is made from clear vinyl, which allows pets to see what is on the other side of the door. This can ease the anxiety of pets who are hesitant to step into a room without knowing what is going on.
How does the Liberty Pet Door contribute to energy efficiency in a home? The flap’s magnetic closures keep the flap closed against wind and rain. The weather stripping lining, as well as the option double flap configuration, adds extra insulation and prevents drafts.
What if my wall is thicker than 8"? We feature other brands of pet doors that will be better suited to your thick walls. The Endura Flap Pet Door for Thick Walls is great for maximum insulation and extreme weather situations, while the Hale Pet Door for Thick Walls is most similar in style to the Liberty Pet Doors, and will be best for pets of varying sizes.
Can a large dog & cat use the same double flap door flaps? We designed the Liberty Pet Door flap for just this situation: to make it easy for pets of varying sizes and strengths to be able to use the same pet door flap. The flap is a clear, UV-protected, moderate weight vinyl and both cats and dogs will find it very easy to use.
Is a single flap enough for extreme winter weather? The Liberty Pet Door functions best in moderate to mild climates. For extreme weather situations, we recommend considering the Endura Flap Pet Door for Walls instead, as they feature a dual-layer flap that provides superior insulation. If a Liberty Pet Door is better suited to your pets, but you still experience weather extremes, we definitely recommend opting for the double flap model.
