A wall pet door for thicker wall construction that keeps the opening more insulated and secure with Endura Flap sealing performance, a telescoping tunnel built for deep installs, and durable aluminum framing for long term ownership.

    Built for homes where wall depth is the deciding factor, this model delivers a clean in wall pet entry when a standard tunnel range is not enough, while keeping the opening more protected for everyday comfort.

    Made for deeper wall construction
    The extra long telescoping aluminum tunnel is sized specifically for thicker wall builds, so the door can span the full depth without relying on a separately fabricated tunnel section. The result is a more consistent fit through the wall and a cleaner finished appearance from inside to outside.

    Comfort in demanding weather
    Endura Flap sealing is built around a flexible flap and a magnetic edge that helps the door stay closed when conditions are active. For buyers dealing with wind or temperature swings, that tighter close reduces the open feeling many basic flaps can create.

    Options that match life's demands
    Single and double flap configurations let you choose the balance that fits your climate and your pet’s comfort level. A locking cover is included to close the opening when you want the door secured, and the aluminum frame is offered in black or white to better match common trim and exterior palettes.

    Made for the long haul
    Made in the USA and backed by a lifetime warranty, this is a wall pet door built for pet owners who want a durable, permanent-feeling solution they can rely on for years.

    Installation & Fit

    • Uses a telescoping tunnel system that spans the entire wall depth without requiring a separately fabricated tunnel section
    • Installs into standard framed wall openings and can also be adapted to masonry and kennel style wall structures with appropriate preparation
    • Mounts internally through the telescoping tunnel section to the wall studs, creating a snug and secure fit
    • Sturdy locking cover top-loads into the interior aluminum frame (for double flap units, you can opt for a second locking cover to close on the exterior frame as well)

    Best Suited For

    Ideal For

    • Homes with thicker wall construction where a standard wall mount tunnel would not span the full depth
    • Buyers who want a dedicated pet entry through a wall instead of sharing a door or sliding door opening
    • Households prioritizing steadier indoor comfort in windy or extreme temperature conditions
    • Installations where a finished look on both sides of the wall matters for the final result

    Not Ideal For

    Questions

    I have a small and large dog sharing this door. Will my small dog be able to open the flaps on the extra large double flap dog door?

    It depends on the tenacity of your small dog. With the Endura flap door for walls you can decrease the magnetic resistance of the threshold on large and extra large sizes making it easier for your small dog to use. You will also want to make sure the door is mounted low enough for the small dog to walk through and high enough to clear the large dog's back. This may mean purchasing a larger flap.

    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 Endura Flap Door Mount to a Wall Mount.

    Are the panels/flaps flexible? Seems like it would trap a dog if it backed up.

    The Endura Flap is slightly more rigid than other economy style flaps, but it is a safe, soft, flexible flap. It remains flexible in temperatures as low as -40°F.
