Quick Fix for Mismeasurement
Adds 1" Height to Panels
Super Simple Installation
These are a part of the exclusive anti-whoops feature included on all Endura Flap patio pet doors. If you mismeasured you might 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 create your own using a 1" piece of wood).
To make your panel slightly shorter, you may trim the flanges that accept the height extension with a metal 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.
