Garage door bottom seal question.
I am hoping at least one BOTL can help me out. We bought an older home and the garage door is older. We love it because it is insulated and still works. The problem is that I need new weather stripping/bottom seal for it and don't know what to get. The door is 21' instead of the common 16' and the weather stripping is an odd shape that stuffs into a single channel. I am not sure where to find a replacement. Any thoughts or ideas?
