Single Flap or Double Flap? This page is the single flap version. See the double flap door mount version. Double flaps would provide more insulation for your home, perfect for climates that experience extreme hot or cold weather. If you live in a more temperate climate the single flap would be enough.

Product Features

  • Extreme weather resistance in heat and cold for maximum insulation value
  • Installs in all types of doors including, but not limited to, solid core doors, hollow core doors, metal doors, storm doors
  • Secure Locking Cover with the strength of 1/16″ of steel to prevent unwanted guests from entering through your doggie door
  • Complete Magnetic seal on three sides keeps the flap shut in winds up to 50 mph
  • Four flap sizes available from small for cats to extra-large for big dogs to accommodate most breeds

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.
