FAQ

Does this dog door insert panel work with vinyl sliders? Yes, the Endura Flap Thermo Panel 3e will work for vinyl sliding glass door so long as the track is at least 1" thick.

When you order in one of the custom height ranges, you will be prompted for your track height. The patio panel will be built to a height that is approximately in the middle of this 3" range. For example, if you specify 40", your panel will be built to adjust from about 38" to 41" tall.

How long will my custom panel take to ship?
