Patio Pacific Endura Flap Pet Door for Doors - Key Features

  • Extreme performance Endura Flap - We get it, you're tired of replacing worn out, leaking flaps. You owe it to yourself to investigate the Endura Flap; the best, most highly engineered pet door flap ever made. It seals, it insulates and it will last forever! By the way, want to see what happens over time to the more traditional vinyl flaps? See our Leaky Flap page!
  • High aspect ratio design - Much easier to fit your pet. Improves security for medium to large sized pets. Easier to share with a smaller pet.
  • Optional Add-on Magnets - Helps to increase the already significant wind resistance of the pet door
  • Solid aluminum extruded framing - Features completely hidden hardware. No more flimsy frames with bolts showing all over.
  • Environmentally safe and friendly material - Green, unlike environmentally harmful vinyl (PVC).
  • Self-framing for all doors - 1/2" - 1 3/4 " single flap version and 1 3/4" to 2 1/4" double flap version. (Adjusting the single flap to less than 1 3/8" requires cutting the trim frame with a jig saw).
  • Sturdy locking cover - Locks pets in or out. Easy to use clip lock is better than the old spring-loaded pin locks. It's equivalent to 1/16" thick steel. 
  • Four sizes - From Small #6 for cats and small dogs to the Extra Large #12 for very big dogs.
  • Superior Warranty - 10 year warranty, 15 year warranty on the Endura Flap Assembly.
  • 100% Designed, engineered and manufactured in the U.S.A.

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


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.

Fabulous Product!!!

Should have ordered this years ago!! This is a great well made product that was easy to install! (once I got past the scary part of cutting into my exterior door) The instructions and guide for cutting the hole were spot on. Idaho weather can fluctuate from one extreme to the next so the double magnetic doors are great for the area. There is not even the slightest breeze coming through. I must admit my 2 Jack Russells took 4-5 days getting used to pushing through but once they figured it out it has been a lifesaver! The only extra thing I added was a little thicker weather stripping as my door has panels and did not lay flush in some spots. Otherwise it fits snug as anything. I highly recommend this product!!! I looked at other cheaper doggie doors that were made of plastic but I am so glad I spent the extra on this metal framed doggie door. I see no reason this shouldn't last a very very long time. A++++ Thank you Pet Pro! Would order this door again in a heartbeat if needed in the future.

We like it!

Very happy with the door and if it lasts for a reasonable amount of time, it will be well worth the money. It took a little bit of training for the dogs with the stiffer and well sealed door but they are completely comfortable with it now.

Excellent Product

This is my second doggy door purchase from Pet Pro Supply. They are long-lasting and well made.

Quite the door!

The door has great sealing ability, to the point that it has taken our timid border collie about two weeks (and the removal of all the bottom magnets) to get comfortable traveling through it. We like that about it!

Not yet installed

If this pet door is as quality as our previous one we will be quite pleased.
