Thermo Panel IIIe with Endura Flap - Bronze (Dark Brown) Frame, Small Flap; 74 3/4"-77 3/4"H


The Patio Pacific Thermo Panel IIIe with Endura Flap is The Best All-Around Pet Patio Panel. The award-winning patio door panel has the Endura™ flap, insulated glass, user-adjustable "Rise", and is highly wind resistant.

Key Features: Easy installation -- doesn't require a drill or other tools. Exclusive User-Adjustable Rise and built-in Anti-Oops in case your measurements were slightly off. Safe and secure with a provision to lock the sliding door, beefy metal framing, and a sturdy locking pet flap cover. Superior insulation -- twice the energy efficiency of single-pane panels. Double-paned low "e" glass with endura flap. Highly wind-resistant with draft stopper. Patented Endura Flap. 100% designed, engineered, and manufactured in USA. 10 year warranty (15 year on flap). Colors are Bronze (dark brown), Satin Aluminum (silver), and White.

Points to Consider: Measure carefully -- both for the flap width (see sizing guide) and the panel height. Make sure to get the correct "rise" size. As a general rule, flap height plus rise should be a bit more than dog's shoulder height. Measure track height at the lowest track wall at the bottom (usually the outside track, between the sidewalls). You'll need enough compression to clear that height.

Patio Pacific Inc

was incorporated in 1976 specifically to market a new type of pet door--the 'panel' pet door for sliding glass door. This new product, the 'Instant' Pet Door, was the first of it's kind to offer an adjustable height capability which was desperately needed because sliding glass door tracks are not all the same height. It is a tribute to Lucile, founder of the company, that she had the vision to see a need in the market and the initiative to start a company from scratch to meet that need.

Over the years, the pet door has gone through many design improvements. And, In 2002, we began looking at the flap problem. Simply put, there wasn't a good flap on the market at the time. Either they were rigid, and therefore not safe enough, or they were flexible and safe but leaked badly, didn't insulate and eventually failed requiring the owner to buy another one and start the process over. I felt that there was a market for a really high quality, durable, safe flap that also sealed and insulated. With a designer's invaluable help, the 'Endura' flap was designed and built. It is, without doubt, the best pet door flap ever made and was the basis for a complete line including patio panels, door mounts and wall mounts by summer of 2005.

Average Rating

door easy to install. flap works good & is very weather proof. add on a charly bar is a must. sliding door will not seal aganst thermo panel without charley bar. know way to use your sliding door & keep the weather out of your home. not a good choice if you want a pet door in a sliding door that you do not want locked from the inside all of the time. THE EDURA FLAP keeps weather out, but the THERMO PANEL does not. in other words , you can not go out your sliding door and shut the door from the outside to keep the cold weather from going into the house. you find all of this out after installing the weather seal. returns after weather seal is installed will cost you money. this pet door is fine if you want to turn your patio sliding door into a pet door only or use your sliding door from the inside. you will have to have someone on the inside , put charley bar in after youy go outside.
