  • Sturdy, well made door
Size: Medium
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.

Fairly easy to install. Was nice and tight with good magnet strength. but after a month or 2, the sun seems to have shrunk it a little, with a little warping.

  • Great Dog Door – Sturdy & Keeps the Cold Out!
Size: Medium
This dog door is exactly what I needed! It’s 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 it’s the perfect size for him. Installation was straightforward, and the telescoping tunnel made it easy to fit our door. I also like the sliding panel—it’s 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. ... show more
