The Endura Flap Vinyl Panel is the most insulated pet door on the market, designed specifically for vinyl-framed sliding glass doors. Unlike other options for a sliding glass door with dog built-in (which generally have a metal frame), this door has a vinyl frame to match the original vinyl of your door and fit more comfortably in the track. This semi-permanent, extreme weather dog 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. This insulated dog door for sliding glass doors is engineered to withstand -40°F and 50 mph winds. The magnets that line the flap ensure the utmost energy efficiency and keep the flap sealed during rough weather for the most extreme weather pet door possible. The Endura vinyl pet door for sliding glass doors also features dual-pane, Low-E glass, which blocks harsh light without compromising the amount of natural light coming in.

How to Measure Your Sliding Glass Door for a Pet Door
How to Adjust Your Endura Flap Magnet Strength
Is this the same as the Thermo Panel 3e?
This is very similar in that it has the same height ranges, flap sizes, Endura Flap, and dual pane Low-e glass. However this one is specifically made to fit better in the wider vinyl slider tracks.
Will this fit all vinyl doors?
This will work in doors that have a recessed track at least 1 1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail
Does it lock?
Can I install it myself?
It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out.
If you can remove it what prevents intruders from taking it out?
The thumb screws are on the inside of the house so you can't loosen them from the outside.
Can you lock the pet door?
It comes with a closing cover, and you slide that in on the inside of the house. It is a very secure ABS plastic material that is as strong as a 1/16" sheet of steel.
Does this insulate well?
This door has superior insulating capabilities! The flap has magnets that seal all the way around, and will stay closed in wind gusts up to 50mph. The dual pane glass also compliments the insulating value of you new vinyl door. It is our #1 recommendation for extreme climates.
What does the recommended pet height mean?
That column is what we recommend be the range of pet height that would be suitable for that particular flap size. So for example if you pet is 20"tall and could fit though a 10" wide opening, then you could go with the large flap.
How to I measure for it?
You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track.
Does it come in any color other than white?
No, but the you can paint the vinyl to match.
What if my track is wider than 1 1/2"?
It can still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly.
Can you adjust the step over at the bottom?
This panel does not have a adjustable step over, but it is pretty low at 4" so most pets should be able to negotiate that just fine. If you aren't sure if your pet can then we recommend simulating the opening with cardboard. You can cut out the flap size you are looking at, making sure that it is 4" from the edge of the cardboard. Then see if they can get through comfortably.
Does your door have to be vinyl?
No, not as long as the track height and width meet the panel specs.
Does it come in a height for 96" sliding doors?
At this time it is not offered in the taller height ranges, but we're working on it!
What are some breeds of dogs these will fit?
Small would be Chihuahuas, Yorkies, and cats. Medium would be good for Corgis, Jack Russell Terriers, and French Bulldogs. Large would fit most Labs, Goldens, and Pit Bulls. Extra Large would be good for most Rottweilers, German Shepherds on the large side, and English Labs.
Is the flap flexible?
It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps.
Is the flap clear?
It is a little foggy, but it is see through.
Will this form condensation like the aluminum panels?
Nope! That is one of the great things about the vinyl framing is you won't have the the condensation on the inside of the house.
How do you replace the flap?
Since this is really our door mount version of the Endura Flap installed onto our vinyl panel you would replace it much like you would one installed in a regular interior/exterior door. This means that you would drill out the hole plugs to remove the screws. Then pull off the flap assembly, switch out the flaps, and reinstall the door onto the panel. All of this can be done without removing the panel from the track.
Is there an electronic version of this panel?
We do hope to offer that option in the future, but right now we are offering only the Endura Flap options.
