Endura Thermo Patio Panel 3e


No need to cut a hole in glass, a door, or a wall. No need to modify your sliding glass door framing. Due to the spring loaded top, no tools are required to install your sliding glass dog door! The adjustment ranges allow your pet door panel to fit a variety of sizes and comes with an “Anti-Whoops” feature if you are moving or have mis-measured your track height. When you move, you can take the sliding glass dog door with you! 

  • Insulated, dual pane, LoE glass, in sturdy aluminum framing
  • Safe and energy efficient single flap for pets
  • No tools are required for installation, perfect for renters or vacation homes
  • Adjustable heights and custom sizes to fit all sliding glass door models
  • Insulation from the dual-paned glass and an energy efficient flap that has magnets on all sides to shield against the cold or heat. The bellows on the side will expand and contract based on the weather to ensure that you have the best seal possible.
  • Easy installation due to the spring loaded top. To install your Endura Flap, place the bottom of your panel into the bottom track, push the spring loaded top down, align it to the top of your sliding glass door frame, slowly release the spring loaded top to fit into your tracks and twist the thumbscrews to lock it into place.
  • The flap rotates on a rod rather than screwed into the frame to avoid extreme wear and tear, making it a longer lasting flap. Because the flap is made of PVC rather than Vinyl, the flap will not warp or yellow in direct heat.
  • Fits into most sliding glass door including aluminum and vinyl frames with a track width minimum of 1”
  • Secure locking cover can be placed over the pet door to ensure that intruders will not be able to come in through the dog door. Locks will also be provided to secure your sliding glass pet door to your frame.
  • User adjustable step over height allows you to tailor the Panel to your pet’s personal size so that they may comfortably use the pet door. This is ideal for dogs with long legs (such as Great Danes) or short legs (such as a Corgi)
  • Option to add or decrease magnet strength to increase already significant wind resistance or training pets.
  • 100% made in the USA

Customized Options:

  • Frosted Glass Option: Your panel may be special ordered with frosted (bathroom) glass to give you extra privacy. This also allows you to partially open your drapes to access the pet door without losing privacy. Frosted glass panels are final sale, no returns, and requires an extra 3-4 weeks to custom order the glass.

Currently Available in white, bronze or tan.
