Dog Doors For Mounting Through A Door


The "Endura" Flap Dog Door for Doors

In2001 Patio Pacific set out to design and build the best pet door flap ever made. We're finally ready to release the resulting flap in a version designed for all doors: The award winning Endura Flap Pet Door for Doors.

If you've never owned a pet door before, you're going to be very satisfied. It does what you think it should.

But if you have ever owned a pet door, hold on to your socks. You're not going to believe how much better this is that what you've had in the past. Please take a look at the Endura flap Pet Door Information that we've provided. We think you'll begin to see what we're so proud of.

A note on single versus double flap versions.

The double flap versions and the #10 and #12 single flap versions are not recommended for use by cats or tiny dogs.


  •  New! Extreme Performance 'Endura' flap - The best, most highly engineered pet door flap ever made.  Tired of replacing worn out, leaking flaps? You owe it to yourself to investigate the Endura Flap. It seals, it insulates and it will last forever!
  •  New! '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.
  •  New!  Provision to add magnets to increase the already significant wind resistance.
  •  Beefy aluminum framing with completely hidden hardware. No more flimsy frames with bolts showing all over.
  •  New! 'Green' flap material:  Safe for the environment unlike vinyl (PVC) which is not.
  •  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.
  •  Superior Customer Protection:  90 day return, 10 year warranty, 15 year warranty on the "Endura" flap assembly
  •   Four sizes - From #6 for cats and small dogs to the #12 for very big dogs.
  •  100% Designed, Engineered and Manufactured in the USA.

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