This replacement piece (for the thrashed one that had been on the bottom of my back door) arrived quickly, undamaged and was easy to install with a few taps of a rubber mallet. We took the door off the hinges and laid it on sawhorses, to do a proper job. So far so good. There is rigid support to the rubber "bubble" pieces that will keep out the dirt and rain.
