Patio Pacific Pet Door for Walls - Key Features:

  • Extreme performance Endura Flap - The Endura Flap is the best and most well engineered pet door flap ever made. It seals and insulates well and will last a lifetime, so unlike other cheap pet doors, you won't have to constantly replace your pet door. For more info on what happens over time to the cheaper, traditional vinyl flaps, see our Leaky Flap page
  • The best fit for your pet(s) - The Endura Flap sizes were intentionally designed with a high aspect ratio design, making it very easy to fit many pets of different sizes. The sizes make it easy to share between very large and very small dogs and cats, while still being small enough to maximize security. Small #6 for cats and small dogs to the Extra Large #12 for very big dogs.
  • Supremely durable and ultra-solid aluminum extruded framing - Unlke other pet doors with flimsy frames and with bolts sticking out everywhere, Patio Pacific designed this in door pet door to feature completely hidden hardware.
  • Green Friendly and Environmentally Safe material - The Endura Flap is made using non-toxic, recyclable, and green for the environment a polyolefin-based polymer (similar to material used in food storage containers). Unfortunately, most pet doors are made with PVC, or vinyl, which is very harmful to the environment. 
  • Self-framing using heavy gauge aluminum tunnel - For all walls to 8" thick (ample for most 2x4 & 2x6 stud walls).
  • Keeps your home safe and secure - An extra sturdy locking cover -  with a strength equivalent to 1/16" thick steel plate helps can keep your pets in AND lock pests of all sizes out. The cover easily clips on and is far easier to use than old style spring-loaded pin locks.
  • Superior quality backed by an industry best warranty - We here at Pet Pro Supply and our manufacturer are so confident in the Endura flap, we have a 15 year warranty on the pet door assembly, which is the longest warranty of any product on the market

Number of Flaps 
1 - Single Flap - On inside frame (same side as locking cover)
2 - Double Flap - One on each side. The included dead-air-space from the second flap adds significantly to the already considerable insulation and sealing capability.

Note: Larger Endura Flaps are not recommended for use by kittens or tiny dogs. Cats have been successful using the Small #06, however a few have found the Medium #08 difficult to use. We would not recommend using the Large #10 or Extra Large #12 or any of the double flap versions for cats.

Questions & Answers

Ask a Question
  • Can the wall mount door be installed thru cinder blocks?

    Thank you for reaching us!

    The Endura wall mounts can frame out a wall that is a maximum of 8" total.  If the wall is thicker than 8" you can get a door mount and frame the wall yourselves to create a tunnel (using plywood, aluminum, etc.).  You will need to make sure in both cases that everything is sealed well. 

    Hope this helped!

    Thank you, 



LTL (less-than-truckload) Freight is used when shipments are 120 lb+ or for oversized equipment, which results in a truck with a large container delivering your order. Our freight carrier will contact you once your order makes it to the distribution center closest to the delivery address specified, and set up an appointment time for delivery.

Pet Pro Supply Co. Free LTL Freight Shipping - Curbside Delivery

Our standard Free Freight Shipping option for LTL deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option to select a shipping location, then this cost is already included in the price.

We strongly recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.

Freight Delivery Locations

This option specifies whether the delivery location is a Commercial, Residential, Residential Business, or a Limited Access address.

  • Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate or are used exclusively for business. Most commercial sites have tractor-trailer access and a loading dock.
  • Residential - If the address used a residence, select this option. This includes Apartment/Condo complexes and dormitories.
  • Residential Business - Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a Residential Business.
  • Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples Include:
    • Place of Worship
    • Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
    • Farms, Ranches, and Rural Areas
    • Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
    • Individual Storage Units
    • Sites - Convention Centers, Construction Sites, Mines
    • Schools and Universities
    • Commercial establishments not open to the walk-in public during normal business hours

Freight Liftgate

A liftgate is a hydraulic lift that is attached to the back of a truck that can lower freight to ground level. Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level. We highly recommend any delivery address without a loading dock, select this option.

However, please know that for certain very long items, such as Kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.

Enduroflap dog door

well made, the metal could be a little thicker, I made sure it had a plywood platform under it to support our 75# dogs weight, I also added a rubber pad to the floor to make it non-slip. I was surprised how fast Our dogs learned how to use this double flap door. For what it is, I think it is over priced, but it was the best I could find and hopefully it will last the rest of my life!


Love the door!! Installation was fairly easy!

Training my puppies

The install went well, although I had to screw it into wood studs instead of using the threaded rods provided. I had to remove and eliminate an electrical outlet by using 2 romex splices and adding 12" of additional romex. I had to place one side up against a stud due to an outside outlet on the other side. I glued a 2x4 on this side and used 4 long screws to hold the door in place. It looks and works great. I like the quality and can't wait to get my dogs trained. I would recommend this dog door due to the weather protection and appearance.

Great door. Took older smaller

Great door. Took older smaller dogs to get the hang of it. I would recommend both door and supplier

The new dog door.

Most surprising, my wife and I installed this on our own! The combination of written instructions and the installation video were very helpful. Luna found it very easy to use. Quality product, really like the positive closing feature of the door. However just this morning, when I walked past the door I felt a cold breeze. I got down to see what was going on. At the bottom of the door is a horizontal sliding piece of the frame. When the door opens this sliding piece of frame drops down and when the door closes it is drawn up by the magnets. This morning, the sliding piece remained dropped down, leaving gap that cold air was flowing through. Is there a cleaning, or lubricating process I need to be aware of. We love this door, we don't want this issue to dim our view. Please forward a solution. Thank you.
