As someone who understands how frustrating it can be to find a pet door that matches the exact measurements of your home, this adjustability is a major plus and provides peace of mind that the product will fit securely and function properly.

Another aspect I appreciate is the openable design of the pet door. Unlike many pet doors that are fixed panels, this one swings inward, which is a clever way to maximize limited space. This feature makes it easier for me (or any homeowner) to move items in and out of the backyard without the door getting in the way. The fact that the manufacturer has even filed for a patent on this mechanism speaks volumes about the uniqueness and innovation behind this product. It’s clear that a lot of thought went into making a pet door that is both practical and user-friendly.

For pet owners with extra-large dogs, this door is a perfect fit.

I can rest easy knowing that my heating or cooling costs won’t skyrocket due to drafts or leaks around the pet door.

It’s worth noting, however, that the installation requires drilling holes into the door frame and that the swing mechanism is fixed – opening inward if installed on the left side and outward if installed on the right. While this design is non-adjustable, it is straightforward, and I appreciate the upfront transparency about this limitation. Knowing this beforehand helped me plan the installation correctly and ensured the door’s function aligned with my home’s layout.

Then, I measured the thickness and height of my sliding glass door to ensure the dog door would fit properly without compromising the door’s function.
