Outstanding conversion kit
I love the new door, it's quite solid and sturdy compared to the original, plastic one. The hinged flaps are perfect and will keep the material from cracking with our wild temperature swings here in Colorado.
My only criticism is that the flaps are completely clear with zero patterns (or privacy), so they show as dirty VERY quickly. I'd definitely recommend a frosted version.
Funny story: the flaps were so clean and clear after installing them, one of my dogs had to be taught how to go through the door again as they totally messed with his head.
