I liked the idea of this garage door seal: a piece in the center to keep the seal itself from collapsing and remaining flat after the door closes. Sounds good, right? Well, theory and reality are two different things. This item arrives rolled up, like a snail's shell, with the 'T' portions flat, and then it's rolled up on itself, flattening the 'O' ring center piece in the process. When I rolled it out to make sure the size was correct for the width of my garage door, I soon realized that the 'O' ring wasn't going to be as O shaped as I hoped, and it was more like a pancake. Now, does that mean this door seal is bad? No, it doesn't. It's a pretty good quality door seal, with a bit thicker rubber than what my garage door originally came with. If you wanted to try to reconstitute the O ring, some online how-to videos suggest trying to stuff an appropriate circumference foam rod into the 'O', but that seems pretty difficult to do. Watch some YouTube videos on how to do this and you'll have an easy time of replacing your existing seal.
