Parts

  • 1 Vinyl Panel Pet Door
  • 1 Weatherstrip Seal
  • 1 Center Post Weather Seal Draft Stopper

Tools

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

Please read instructions & notes thoroughly before installation.

Step 1 Remove the Bottom Crosspiece

  • Lay the entire panel on a flat surface. Using a #2 Philips head screwdriver, remove the bottom set of side-screws. Loosen the middle set of side-screws one turn.
  • Remove the bottom crosspiece by sliding it down and out from the panel.
  • Now that the bottom crosspiece is removed, the remaining pet door assembly, adjustable spacer(s), and adjustable seal extrusions(s) can be removed by sliding the sections down and out of the panel.

Step 2 Adjust Stepover Height

  • Replace the pet door assembly, adjustable spacer(s), adjustable seal extrusions(s), and bottom crosspiece by sliding them back in a different order to achieve the desired height. You can move the spacer(s) above or below the pet door assembly to lower or raise the flap height.

Step 3 Reassemble Panel

  • Once the desired flap height is achieved, replace and tighten the bottom side-screws and tighten the middle side-screws.
  • 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 4 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 5 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 6 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 7 Place Panel In Track

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

Step 8 Install the Draft Stopper

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
  • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
  • This strip prevents air from leaking between the sliding glass door and the stationary panel.
  • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
  • Repeat step two to install the panel in your track.

Adjusting 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 Remove Side Magnets for Easier Use

FAQ

Is this the same as the Thermo Panel 3e sliding glass dog door insert?

This is very similar in that it has the same height ranges, flap sizes, and Low-e glass. However, this vinyl panel is specifically made to fit better in the wider vinyl slider tracks. Read about the differences between vinyl and aluminum pet door panels here.

Will it fit all vinyl sliding glass doors?

This panel fits 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 the flap lock?

The vinyl sliding dog door panel comes with a secure locking cover to block access to the flap when needed.

Can an intruder remove the sliding glass door dog door from the outside?

No. The thumbscrews on the sliding glass door dog door insert are on the inside of the house so you cannot loosen them from the outside.

Does the doggy door lock?

We do include a c-clamp lock to lock the panel in place in your slider track. However, the sliding door dog door panel does not mate with your existing sliding door lock. You can also use a Charley bar or wooden dowel for additional security.

Does this vinyl pet patio door panel insulate well?

Yes, the vinyl sliding pet door insulates very well. The flap is lined with magnets on three sides to stay shut in winds up to 50mph. The glass in the sliding pet door panel is Low-E for maximum insulation.

How do I measure for a dog door for sliding glass doors?

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 for your track height.

Does the sliding door dog door insert come in any color other than white?

No, but the vinyl sliding glass pet door can be painted to match your home.

What if my track is wider than 1-1/2"?

It will 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, this can work for aluminum sliders with tracks at least 1.5" thick.

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 so it's easy for pets to use.

Will this form condensation like the aluminum panels?

Nope! One of the benefits of a vinyl pet door for vinyl sliding doors is that it won't "sweat" in cold weather the way aluminum panels can.

I really like how the door fits next to my sliding glass door because it is so sturdy, no heat or air loss from my house because of the quality of the door. The size of the flap is perfect for my little dog.

Quality Dog Door

Install was easy once I had the right size door (my mistake). The flap is secure, one of my dogs picked it up easily while the other is still having trouble (dog problem, not door problem). Overall, this matches our vinyl sliding glass door perfectly and brings a quality look to something that could otherwise look cheap and stand out like a sore thumb.

Works great!

We purchased this door to replace an old leaky one. My hallway, where the door is installed, now stays a consistent temperature. I had to remove the side magnets for my elderly cat to finally use the door. I would highly recommend. Worth the money.
