Broken Bottom trim on outdoor front door

Thanks for posting. It appears you need a new door sweep. Without seeing the end profile of your old one I can't be totally certain what might work, but the design seems to resemble our 40-001. See the end profile dimensions below to determine if it matches up with your old sweep.

An alternative solution would be to go with an entirely different design like our 58-176. This wraps around the bottom of the door and is mounted to one side. Take a look and see what you think.
