Product Details


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.

Features:

  • Best dog door for cold weather (two flaps for enhanced insulation)
  • Pet flaps range from small to extra large
  • Fits into existing tracks a minimum of  1 1/2" thick, occupying space in the door opening
  • Vinyl Panel comes in two adjustable track height ranges:
      • 74-3/4" to 77-3/4"
      • 77-1/4" to 80-1/4"
  • Quality of flap ensures that it stays flexible in extreme temperatures
  • Magnets withstand drafts, leaks, and heavy wind
  • Flexible flap swings on a rod at the top to avoid cracking and flexing
  • Includes a secure locking cover and c-clamp lock
  • 90-day return policy and a lifetime warranty

Benefits:

  • Vinyl frame applies seamlessly into the track for a highly insulating fit
  • Panel can be removed at any time with the semi-permanent, spring-load design
  • Steer clear from cutting holes or making any permanent changes to your door
  • Comes in white to match the interior design of the existing sliding glass door
  • Sturdy locking cover allows you to secure the door when necessary
  • Gives dogs the freedom to access the outdoors without needing you to let them out
  • Structurally sound design is built to last

Parts

  • 1 Vinyl Panel Pet Door
  • 1 Weatherstrip Seal Roll

Tools

  • #2 Philips head screw driver
  • Non-metal hammer
  • Scissors

Please read instructions & notes thoroughly before installation.

Step 1 Separate Flap Frames

  • Lay the entire panel on a flat surface. Use a #2 Philips head screwdriver to unscrew the four frame screws from the flap frames to separate them, then set them aside.

Step 2 Loosen Side-Screws

  • Loosen both the middle and bottom sets of side-screws by one turn.

Step 3 Adjust Stepover Height

  • Once the bottom and middle side-screws are loosened, slide the spacer(s) down to the bottom of the panel. Pull the adjustable seal extrusion(s) down and out to place it between the adjustable spacer and the adjacent crosspiece.
  • You can move the spacer(s) above or below the flap to raise or lower it until the desired flap height is achieved.

Step 4 Replace Side and Middle Screws

  • Once the desired flap height is achieved, replace and tighten the bottom side-screws and tighten the middle side-screws.

Step 5 Reattach Flap Frames

  • To reinstate the pet door assembly, sandwich the interior and exterior frames on either side of the pane how they came. Insert the four frame screws through the pet door frames.
  • Do not fully tighten the screws until all four are inserted and the pet door is leveled.
  • If the white connector pieces fall off of the Bottom Crosspiece, this step's diagram pictures how to orient the connector back onto both sides of the Bottom Crosspiece.

Step 6 Add Hole Plugs

  • Use the wooden of a hammer, a rubber mallet, or another non-metal tool to tap the hole plugs over the eight exposed frame screws.

Step 7 Loosen Height Adjustment Locks

  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.

Step 8 Insert Panel Into Track

  • Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
  • If you can’t clear the track, try swinging in from the outside, as the outside track wall may be shorter. If the panel still doesn’t fit, see the FAQ for guidance.

Step 9 Apply Weatherstrip

  • Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
  • Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.

Step 10 Place Panel In Track

  • Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.

How to Adjust Stepover Height

FAQ

What if my panel is slightly too tall?

You can trim up to 5/16" off the spring-loaded adjustment piece at the top. Remove the adjustment piece with a #2 Philips head screwdriver and use scissors to cut down the flanges. Be careful not to cut too low.

What if my panel is slightly too short?

We ofer height extensions that will add 1 1/2" to the top of the panel that you slide into the channel at the top. These are made from the same vinyl as the panel so the color will match exactly. If the extension makes the panel feel unstable, you can secure it with screws.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1 1/2", you can use small wooden shims or extra weather-stripping to fill the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel.

Locking Your Door

Since you cannot lock your sliding glass door to the panel, we have provided you with a sliding door clamp lock to secure your home.

Installing the sliding door clamp:

This clamp as a screw that tightens by hand to prevent the sliding door from moving beyond the clamp's placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door's raised track.

If you aren't able to use the lock that comes with the panel:

A great alternative to locking your sliding glass door is a Charley bar or dowel. Both block the slider from opening. When engaged, you cannot pull the sliding door away from the pet door panel.

How to Measure Your Sliding Glass Door for a Pet Door





How to Adjust Your Endura Flap Magnet Strength



FAQ

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?

We do include a c-clamp lock. It is not designed to mate with your existing sliding door lock. You can also use a Charley-Bar or dowel in the track.

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.

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.
