Description

The Endura Flap Horizontal Window Pet Door is an aluminum-framed dog door designed to keep your home insulated in 50 mph winds and extreme temperatures as low as -40℉. Engineered with Low-E, energy-efficient glass, the Horizontal Window Panel Pet Door blocks harsh UV rays and keeps your home’s interior temperature regulated and comfortable. Each panel has a 3-inch adjustment range to accommodate various track heights. Every Endura Flap Pet Door comes are made to last a lifetime! If there is ever an issue, our responsive team will get it fixed at no charge to you. Endura Flap is made in the USA and focuses on quality. Most other pet doors are not built to last or effectively insulate your home. Most Endura Flap customers are pet owners replacing their existing, low-quality pet door for a superior model. Endura Flap offers easy, no questions asked returns. Endura Flap's are made with sturdy aluminum frames and a patented polymer flap to ensure high quality production. The roots of Endura Flap Pet Doors go back to the year 1976, when we were primarily a mail-order catalog business. Engineered with quality as our primary goal here in the USA. We strive to make the best pet door on the market, not the cheapest. When installing the Endura Flap wall mount doggie door you want it to clear the top of your dog's back by at least 1". You also want the step over to be comfortable, no more than 1/3 of your pet's shoulder height. With 4 sizes available, the Endura Flap Pet Door has options that work for small cats up to 36" tall dogs The step-over is the part of the sliding glass door panel under the actual flap opening. Door and Wall Mounts are available in white, black, and tan. Glass Panel Products are available in white, black, and silver. The magnetic flap seals tightly to insulate against the weather. All doors also come with additional weather protection, like weatherstripping and sealant. The polyolefin polymer flap is lined with magnets for a complete seal, ensuring that the flap stays shut in winds up to 50 mph. A single Endura Flap is extremely energy-efficient and capable of withstanding winds up to 50 mph. However, the double flap option is the most insulating Yes! The flap and frames are identical. The only difference between the two models is the hardware that is included for installation. All locking covers slide in from the top. If you purchase a double flap model, the locking cover can be used on the inside or outside frame. Since 1976, we have had over 500,000 satisfied customers

Great quality, sturdy build
Color: Black Size: 57"-60" Window Height
Works perfectly! I ordered the 57"-60" size, my windows are 60" height and just over an inch wide inside the tracks. Once the bolts are loosened at the top, the top can be pushed downward to maneuver into the window space. I had to adjust the size downward, then tightened the bolts to hold the top in place before putting the door in the window as it was a bit difficult to hold otherwise, the springs inside are very strong. Once in the window, I loosened the bolts and let the top slide up into place. Works great, great quality, perfect fit. I had to remove the flap because I have my original cat door in the screen and the screen blocks the cat door from swinging out. It was pretty easy to do. Adjusting the height of the cat door at the bottom was easy as well. There are instructions which work well and helpful. Now I won't need to open the window so the cat can get out. I'm very happy with this purchase, I recommend. ... show more

Does the job!
Color: White Size: 6" x 11"
Fairly easy to install. Had to trim off some metal, which is part of the design, so be prepared for that. We get heavy winds out in the country and the door still stayed closed, which was impressive. I just wish there was an attachment that would prevent the cat from bringing in mice and lizards, lol. ... show more

Really Cool Cat Doorfor a Side Sliding Window
Color: White Size: 43"-46" Window Height
The panel was super easy to install and is very sturdy. My window is a 46 inch long window, so I ordered the 43 inch- 46 inch size. The spring loaded extension is released by turning the screws located about 8 inches from the top. They provide a strip of weather Stripping that is supposed to go on the gap of the open window, but they did not provide enough length, so I will have to go get some, which is another expense for a little but of stripping. So many people have complained about this, you would think they would have added a little more, but no they did not. For such an expensive door, you would think they would. ... show more

Strong and Sturdy
Color: White Size: 6x11 inches
It was very easy and efficient. I've previously had an old one prior to this aluminum frame... I wanted to be certain if they would learn how to use it, before investing something big and durable for them. Wel, it definitely succeeded from their experience of learning how to use it for this great investment on aluminum rather than ABS plastic I once got them prior. ... show more

Does not fit a 46” window
Color: White Size: 6" x 11"
It didn’t fit. I measured many times and my window is 46” exactly. This window measurement does not take into account the sill height or the height of the edge of the window channel. Not certain trimming would have worked either. Didn’t risk it. Sent it back.
