Installation & Fit

  • Designed for straightforward DIY installation using standard household tools like a drill and jigsaw; consult a contractor if you are not fully comfortable with this type of work
  • The self-framing tunnel wraps the internal cutout for a clean, professional finish without custom carpentry
  • Requires a flat mounting surface on your door; avoid placing over deep decorative molding or glass inserts (if you have a French Door, the Utah Pet Access French Door Glass Insert may be better suited)
  • Ensure the flap width is at least 2 inches wider than your pet’s widest point for comfortable passage
  • Mount the top of the flap 1 to 2 inches above the pet’s shoulder to prevent crouching or back injury
  • Keep the step-over height as low as possible to accommodate your pet as they age or if they have limited mobility
  • Flexible mounting heights allow you to customize the opening to the specific height of your dog or cat

Best Suited For

The Endura Flap Pet Door for Doors is ideal for:

  • Extreme weather climates with very hot summers, or very cold winters
  • Door thickness of 1/2" to 2 3/8" (see the Endura Flap Pet Door for Thin Doors if your door is less than 1 1/8" thick)
  • Homeowners prioritizing durability and longevity: this door is covered by a lifetime warranty!
  • Solid-core, hollow-core, metal, aluminum or steel doors

Not Ideal For

  • Temporary installations or rental properties
  • Pet families with both large dogs, and very small dogs or cats, as the smaller pets may have difficulty with the heavier flaps (the Liberty Pet Door for Doors may be a better fit)
Product Details

Product Details


The Endura Flap Pet Door for Doors is made for homeowners who want effortless pet access without sacrificing the comfort, efficiency, and security of their home. It is crafted as a premium door insert with a tighter seal and enduring construction compared to typical pet doors.

The Endura Flap is designed to help keep the temperature more consistent near the door and reduce unwanted airflow during stormy weather. The flap uses a three side magnetic seal that helps it close cleanly after each pass through and stand up to wind pressure that can work lesser flaps open. It is rated for wind gusts up to 50 mph.

Energy efficiency is built into the flap itself. The dual layer flap design helps slow heat transfer by using trapped air as a barrier, similar to the way an insulated window works. The result is dependable weather resistance in all seasons.

Security is paramount, and the included heavy duty locking cover, equivalent to 16 gauge steel, helps keep your home protected when the door is not in use. 

Fit should feel confident, not uncertain. This model is made for standard interior and exterior doors and is available in single flap and double flap configurations. Consult the size chart to choose the opening size for your pet and confirm door thickness so the frame seats properly and the seal performs as intended.

Have a door less than 1-1/8" thick? Check out the Endura Flap Pet Door for Thin Doors.

You can also tailor how the door feels for your pet and your climate. Magnet strength can be adjusted so timid pets have an easier push through, while windy conditions can be matched with a stronger closing seal. Adjustment guidance is provided in the Removing Side Magnets video in the Videos section.

Built in the USA and backed by a Lifetime Warranty, the Endura Flap is designed for long term performance you can trust.
