PERFECT PET The All-Weather Energy Efficient Dog Door, Super Large, 15" x 23.5" Flap Size

It's up and working great. Here's what we learned.1. Know what your door is made out of and use the proper tools for it. Our door is metal over foam. We didn't know this when we started, so we tried using a regular drill bit. Don't, unless you like heating up your drill, acrid smoke, and terrible smells.Once we got a jigsaw blade and drill bits for metal, installation went a lot smoother.2. You can install the dog door without removing the door from the hinges first. We have pets, so it was easier for us to leave it hanging during the install.3. You can install the dog door on a raised panel door. Just fill in the gaps with silicon caulk to seal it once it's in place. There is also already a silicon seal on the exterior of the dog door which works great.The angled edges of the raised panels are tricky but not impossible to drill through. Mark well and take your time.The included cutting template worked really well. We attached it with painter's tape as we used it on both sides of the door. We marked the inside of the door with the template, removed the template, drilled through the door, made the cuts on the inside with the jigsaw, repositioned the template on the outside using the drilled holes as references, marked the cutout for the template on the outside, removed the template, and cut the outside.4. Lay out all your tools and safety equipment first so you don't have to stop partway through to go find anything. For metal skin doors, we used a long sleeve shirt, long pants, boots, gloves, and safety goggles that cover around your eyes too, and a face mask. The flying bits of metal are no joke.If your door is metal skinned, hearing protection is another must. The sound of metal cutting through metal is very loud and painful.5. You can use a skill saw or a jigsaw for the cutout. We used a jigsaw with a blade for cutting metal.6. Clean as you go. We used the nozzle attachment on an upright vacuum and a soft, fine bristled broom and dustpan. A shop vac would also work.We're entirely on hard surfaces and those worked, but wouldn't be enough over carpet so please put down a dropcloth first. You don't want your pet to get into any insulation and metal bits.7. Take your time. Despite what you may see on YouTube, this will take more than 20 minutes, especially if you clean up afterward.Overall installation went well but was challenging, and that's our fault because we were not using the right tools at the beginning. The door works great and is really well made. We're looking forward to it lasting for years.

Sehr gute Qualität und es funktioniert genau so, wie es soll.

I've had a number of pet doors over the last 25 years, this is the noticeably the best one yet as far as construction and insulating ability are concerned. Hopefully the long term durability is as good as its overall construction initially indicate. It's so superior to the Pet Safe doors that I am almost embarrassed that I did not try one sooner. The XL is a little taller than a Large Pet Safe door but is the pretty much the same width, so opening modification was easy.

Great pet door.Prevents both dust or cold air gets in.Easy to install.

It does an excellent job.
