The Endura Flap Pet Door for Sliding Glass Doors - The Original Thermo Panel III Patio Pet Door - was a major upgrade to the very successful Thermo Panel II. The difference was that the Thermo Panel III used the new award winning "Endura" flap--the best pet door flap ever made--while the Thermo Panel II used flaps and framing made by other manufacturers. The benefits of the Endura Flap are far more important than whether the glass is single pane or dual pane.

Now introducing the Thermo Panel IIIe - All of the features of the Thermo Panel III with the addition of "Low E" glass for the insulated glass units. Low E glass consists of a special coating on the inside of the unit which greatly improves the energy efficiency of the insulated glass unit.

Hot Tip: People almost always visually over-estimate the width of the flap needed by their dog. To avoid this problem, call the dog through a doorway opened only enough for him to comfortably  pass. Then measure the gap.  Then measure the height of the dog at the withers (top of the shoulder).  Inspect the chart to the right to ensure that your pet is no taller than the maximum height value available for  that model. If your pet is taller than the maximum or if you need a shorter rise (for another,  smaller pet for example) go up to a larger size.

We will design a panel especially for you with a height adjustment range of 3" that has your measurement approximately in the center of that range. Custom height orders may not be made by phone. Model Minimum Maximum # 6 40" 96" # 8 46" 96" # 10 49" 96" # 12 58" 96" 1 'Rise' is the height of the flap above the base of the pet door. We suggest that 'flap height' + 'rise' 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 rise dimensions shown in 2" increments. Here's more info on the 'Adjustable Rise'. Custom orders cannot be resold. Therefore, they must be a final sale once built. Note that the insulated glass units for custom height orders take three to four weeks for delivery from the tempering plant and that we need about 1-2 weeks to schedule the assembly after the glass unit arrives. Warranty Endura Flap Information Adjustable Rise Info Installation Replacement Parts   Thanks for everything.  I received both panel doors on Friday!!!  Thanks to you and your intervention, they came in the color I wanted (white) and not the color I accidentally originally ordered (bronze).  I already installed  them (super easy). My four dogs are so excited that I catch them just having fun going in the door, turn around, go out the door, turn around, go back in, etc.  For now, it's their new toy.  I do hope the novelty wears off soon!!!  I was thrilled and surprised at how quickly they arrived.  I will highly recommend Pacific Patio Pet Doors.  Sincerely,  Another satisfied repeat customer,  Joan M., Simi Valley, CA We got the Thermo Panel III today and installed it in less than a half hour. I'm impressed with the quality, industrial-strength nature of the product. "First dog" got the hang of it after a few of the included treats enticed her through. "Next dog" is a little shyer, but is learning from watching her sister. I'm impressed with the engineering of the product. So glad I waited a few weeks to get the best. Thanks.
