 The Endura Flap Vinyl Panel is the most insulating cat door on the market, designed specifically for vinyl-framed sliding glass doors of any size. Unlike other metal frames common among sliding glass door panels, the vinyl frame fits more comfortably in the track and matches the original vinyl of your sliding glass door. This semi-permanent pet door has a spring-loaded design, which means that no tools are necessary for installation. It safely secures the panel in place without making any permanent alterations, which is ideal for rentals and vacation homes! Engineered to withstand -40 degree weather and 50 mph winds, the magnets that line the flap ensure the utmost energy efficiency and keep the flap sealed during rough weather. The vinyl panel also features dual-pane, Low-E glass, which blocks harsh light without compromising the amount of natural lights coming in.


  • Fits into existing 1 ½ - 1 ¾ thick track of your vinyl door, occupying space in the door opening
  • Vinyl Panel comes in three adjustable track height ranges:
    • 74 ¾ - 77 ¾
    • 77 ¼ - 80 ¼
  • Quality of flap ensures that it stays flexible in extreme temperatures
  • Magnets withstand drafts, leaks, and heavy wind
  • Flexible flap swings on a rod at the top to avoid cracking and flexing
  • Includes a secure locking cover
  • 90-day return policy and lifetime warranty 


  • Vinyl frame applies seamlessly into the track for a highly insulating fit
  • The panel can be removed at any time with the semi-permanent, spring-load design
  • Steer clear from cutting holes or making any permanent changes to your door
  • Comes in white to match the interior design of the existing sliding glass door
  • Sturdy locking cover allows you to secure the door when necessary
  • Gives cats the freedom to access the outdoors without needing you to let them out
  • Structurally sound design is built to last
