Endura Flap Patio Panel Height Extensions

These are a part of the exclusive anti-whoops feature included on all Endura Flap patio pet doors.

You mis-measured! Now you have to send the patio pet door back for the correct size. Not so fast! If you purchased a Patio Pacific patio pet door, you may be able to salvage the situation by using the "anti-whoops" feature:

  • To make your panel about 1" taller, you may purchase a height extension (or make your own using 1" x lumber).
  • To make your panel slightly shorter you may trim the flanges that accept the height extension with a hacksaw.

If you need a substantially higher panel that doesn't fall into the standard Patio Pacific height adjustment ranges, then you may purchase a custom height Endura Flap Sliding Glass Pet Door.

NOTE: The size of the height extension is about 3/4 inch. Choose your patio panel pet door size based on the chart above so we can send you the right width. If the height extension of 3/4" is not the correct size, you can also put a piece of lumber in your panel's track to extend the height.
