Then study the comparison chart and read the information on the patio panel FAQ page which cover the fine points of patio pet doors.

Note Endura Flaps™ are not recommended for use by kittens or tiny dogs. Cats have been successful using all four sizes.

1 step-over is the height of the flap above the base of the pet door.We suggest that 'flap height' + 'step-over' should about equal pet shoulder height. Unlike any other panel pet door on the market, the Thermo Panel IIIe can be adjusted by the user to the step-over dimensions shown in 2" increments. Here's more info on the user-adjustable step-over.

Highly recommend review by Barb

Just received this door less than 48 hours ago, and I'm not sure who loves it more, me or the dog. At first, she was scared of it and ran. Then she got the nerve to come closer, but just stared at it like a calf at a new gate. But, within 24 hours, she was going in and out of her new door like a pro. I love the new freedom it give us both, and truly appreciate the quality and craftsmanship. HIGHLY recommend.

Very Pleased review by Tom

After doing a lot of online research, and talking a couple of times with Patio Pacific customer service (who were very helpful), we ordered this door w/ 2-day delivery. It was delivered on time and in good shape. Unpacking was easy, the installation directions were clear, and it appears to be an excellent product. As we live in an older house with "replacement" sliding glass doors, everything was a little bit out of plumb, but nothing anyone with a bit of handyman experience couldn't handle easily. While the "Bug Warden" is included, it seems to me that if you properly install the weatherstripping, you have a good bug barrier. At least at first blush, I would say we are extremely pleased with the product, as is our 70 pound yellow lab pub, who, with about 15 minutes' coaching, has already learned that he has his own door.

EXCELLENT-- Wish I Would Have Ordered This Sooner! review by Barb K (Indiana)

When contemplating ordering this door 18 months ago, I was hesitant to purchase such a large, fragile and costly item on-line. I have suffered for the past 18 months with a less-than-desirable, home-made alternative and finally decided to take the risk. I placed my order on a Monday and received it just 4 days later on Friday. The shipment was delivered well packaged and undamaged. I had it in place in just a few minutes and couldn't be more pleased. Before ordering this one, I had tried another brand which was cheaper and available at my local Lowe's or Home Depot store, but it didn't work because the step-over rise was too high. This is the only door on the market with a low step-over rise (adjustable) and an extra large flap opening, which is very important for small dogs and aging dogs. You'll find that all other brands will increase the height of the rise as the size of the flap gets larger, but that won't work if you have a small dog as well as a large dog. Again, I held off on purchasing this one partly because of the cost and secondly for the difficulty in returning the item if it didn't work out. I can guarantee that if you measure your door correctly and follow the tips on the website, the door will fit perfectly. I have 3 dogs and 3 cats. My medium-sized beagle had the flap figured out within 5 minutes, and then taught my larger and smaller dogs how to get in and out. I just can't say enough about the quality of this door. It's an EXCELLENT, EXCELLENT product and well worth the cost!

I just wanted to let you know how pleased I am with your product review by Craig N.

I recently purchased a Thermo Panel IIIe pet door from you. At first I was hesitant to spend that much on a dog door sight unseen. But after doing LOTS of research on the internet and reading almost all the reviews available, I decided to take the plunge.

I was looking for a well built door, possibly double paned glass and with easy installation. After looking at what types of doors the major retailers were selling, both online and brick and mortar stores, none had what I was looking for exactly. I also needed it delivered to me quickly, within a week of placing the order as well.

I placed my order on a Monday, online and before noon, thinking I will receive it on Thursday or Friday of that week. To my surprise it arrived on Wednesday!!, a mere 48 hours of placing my order. It came very well packaged and not damaged. It was sooooo easy to install, well under a hour. Actually, it took me longer to get the door out of the box than to install it (you really use some heavy duty glue on your boxes!).

I have a Cardigan Welsh Corgi mix named Bailey, so he has very short legs, but a normal sized body. Having the options with your door as far as the rise height, was a major selling point. I also followed your instructions to the letter about measuring my dog correctly to get the right sized door, which turned out to be a medium. Upon installing the door and seeing the size of the opening, I said to myself, "It's too small". But I remembered reading on your website that's what it's supposed to look like. But I was still doubtful.

I started to treat train Bailey as soon as the door was installed and amazingly he fit through the door perfectly!! I have the rise set to the lowest point and he doesn't need to jump over it to use the door and his body doesn't rub the sides of the door either. It took him a couple of hours to learn to use his head to push open the flap. At first he would stop at the door and sniff around then gently use his head to push the flap and walk through. I had taken off the metal piece on the bottom of the flap and removed the magnet, so the door would open easily.

Now a week after installing the door, Bailey hits that door at full running speed to go in or out. I think he thinks it's some type of game.
But the flap is so well made, I have no concerns about it's construction holding up to the abuse. I also have an indoor thermometer set up very close to the dog door and have noticed that there is absolutely no change in the temperature after installing the door. There are no gaps and I don't feel any air moving around the frame. It is a very well constructed unit and very well insulated.

I just wanted to let you know how pleased I am with your product and if the situation were to come again on needing another dog door, you will definitely get my business.

We are the next generation of dogs!! review by Sue

Believe it or not, I have had this door for approximately 18 years!! I am amazed that I had 3 dogs that have all passed on at ages above 13 years and we now have another set of 3 pups that are still using the same door! I cannot say enough about the durability and quality. There is nothing like it!

Superb Features review by Todd

I have had this pet door for around 2 years. I live in the Pacific Northwest in the Columbia River Gorge - high winds, rain, sleet, snow, blazing hot summers. This door is superb - seals tight. The pet door flap has a magnetized bottom that, at the bottom of its swing, "attracts" the bottom frame piece that floats up and down about a 1/2 in. As a Mechanical Engineer, I am impressed with its simple yet functional and innovative design. It is very adjustable. The quality is top notch. The pet door panel as a unit probably seals better than the sliding glass door itself.

I highly recommend this door. I also purchased a security bar kit and rubber sealing kit to help block bugs around the sliding screen door. ( I forget the nomenclature used by the website for these additional options.) It all works very well with good instructions.

My only complaint - which is extremely minor in nature - is that it did not come with enough self-adhesive sealing strip. No worries. A quick trip to the local hardware store, at a minor expense, purchased another roll of wide adhesive sealing strip, most of which is still in my garage.

THANK YOU!! for this flap review by cassie

I have had multiple house dogs for years and have gone thru many a flap on various patio dog doors. The flaps would tear with the heavy use of multiple dogs, the replacements did not fit or were not available, the frame around the door cracked, the screws came out, you name it. And the flaps never closed securely, allowing air to leak around the sides and a windy day would blow them open.

This flap is everything they claim it to be. It seals tightly on the bottom and sides. It flexes and the top pivots in such a way that it doesn't tear. After six months of constant use by EIGHT dogs the flap still works as designed without tears. My biggest dog weighs in at about 70 pounds, so I got the large size. My smallest dog is only 10.5 pounds and 13 inches tall at the shoulder. I wondered if he would be able to open the flap since the magnets hold it securely to the frame. But he figured it out within a day.

I was skeptical reading the claims for this flap, and hesitated whether to pay the extra money for this rather than the other brands I had tried before. I am glad I opened up the wallet and ordered. My 8 dogs and I highly recommend it.

They work GREAT review by Jeff A

Just wanted to thank you SO MUCH, both for your excellent customer service (answering all my dumb and paranoid questions), AND a truly amazing product.

I installed one Thermo Panel III between my house and my sunroom (which can get hot or cold), and another between the sunroom and outdoors so my dog can be in, in the sunroom, or outside.

They work GREAT. I did a semi-custom install next to the non-moving slider panels so I could insulate well and still use my locks. Your insulation was excellent (nice and thick, and the slider-to-fixed-panel-seal was first rate), and I added a bit more for my custom situation. And the Endura doors are fabulous. I taped the bottom down to start so they have a bit less resistance in the learning phase. It comes off tomorrow.

Thanks again to you and your whole crew for providing everything I could have asked for and more.
