Sturdy, well made door
These doors are well made and not cheap feeling. I like the design with the insulation layer and locking feature. We haven’t installed it yet, but looks easy and should fit well.

Great Dog Door â Sturdy & Keeps the Cold Out!
This dog door is exactly what I needed! Itâs well-made with strong aluminum, and the three flaps help keep the cold air out, which is great in the winter. My dog (about 30 lbs) had no problem getting used to it, and itâs the perfect size for him. Installation was straightforward, and the telescoping tunnel made it easy to fit our door. I also like the sliding panelâitâs handy when I want to keep my dog inside at night. Definitely a solid, heavy-duty pet door that does the job well! Highly recommend.

Working great so far.
Recently got a new house and a new doggy door for my dogs. Didnât want to deal with their flimsy snap-on panel for the winter, so went ahead and bought this as the aluminum sliding panel is excellent. Really happy with it so far and the magnets appear to be really strong on each side. Time will tell if it holds up, but working great so far.

Excellent dog door
This feels very sturdy and well made. Since this is going to be installed in my kennel, I appreciate the 3 flap design to provide better weather protection.

Dog Door for Door All Aluminum 3 Flaps White, Large Dog Doggy Doggie Door
This heavy-duty doggie door arrived intact and in new condition, well protected using custom cut foam padding, within a branded box. The installation guide looks to have been professionally produced. It was well-worded and offered plenty of diagrams to illustrate installation. The cut-out template is quite handy and helping with getting the size right. The door and its flaps feel well built and durable. It is aesthetically pleasing, as well.

The insulated flap work well!
I installed this in the bottom of a heavy duty door. Now our dog can be let out on our porch and she will go right through the dog door and come back without us having to go let her out the door. When we need to keep the dog in the house, we just need to close the door panel. This all gives us a lot of convenience.The third flap, the insulated flap, has been very effective in blocking cold air from entering my house this winter.
