Size Chart

Single flap or double flap? Double flaps would provide more insulation for your home, perfect for climates that experience extreme hot or cold weather. ‚ There would be a flap on each side and dead air space in between to add extra insulation.‚ The single flap‚ will be more than enough if you live in a more temperate climate. The flap would be on the inside of the wall on the same side as the locking cover.‚ View‚ the single flap‚ version.

Rainwater in the tunnel

The single flap version has a high threshold on the inside and no barrier to the outside. Wind-driven rain will surely enter the tunnel but quickly exit toward the outside.

The double flap version has a high threshold barrier on both sides. Very little water will penetrate the outside flap but any water that does will remain inside the tunnel until it dries.

As with all "wall mount" dog doors, careful caulking of all seams is vital to prevent water penetration inside your walls.

Note:‚ Endura Flap‚ pet doors are not recommended for use by kittens or very small 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.‚
