The "Endura Flap" Quick Panel III patio pet door is identical to the Thermo Panel III except for the use of single pane glass instead of dual pane glass. It is appropriate for more temperate climates or where a lighter weight panel is desired. The benefits of the Endura Flap are far more important than whether the glass is single pane or dual pane.

The difference between this panel and the earlier Quick Panel II is that the Quick Panel III uses the new 'Endura' flap--the best performing pet door flap ever made--while the Quick Panel II uses flap assemblies made by other manufacturers.

Extreme Performance 'Endura' flap - The best performing pet door flap ever made. Tired of replacing worn out, leaking flaps? You owe it to yourself to investigate the Endura Flap. See the full story here. Want to see an example of a popular leaker after some use?

Patented, exclusive 'User Adjustable Rise': Lets the user easily adjust the height of the flap above the base of the pet door to fit taller or shorter dogs (see graphic). This greatly increases the flexibility of the pet door for the future.
 

'High Aspect Ratio' design: Much easier to fit your pet. Improves security for medium to large sized pets. Easier to share with a smaller pet.

User-adjustable magnet strength: Patio Pacific will offer magnet kits which allow the customer to increase wind resistance or reduce magnet pull for training. Each kit will contain 2 sets of magnets (top and bottom) plus installation clips and instructions.
