Exact match for my exterior door - I believe it is a Therma-Tru from Lowes. My old door seal was in desperate need of replacement, letting water into my shed. This took care of my problem with excellence - great design that helps keep water from getting near the actual seal, which of course will keep any water that gets that far from going any further. This gave me peace of mind.
Nice Seal

This review is in regard to the Db370 Notchkrf 36" BGE, as a replacement for one that was nearly 20 years old.
Importantly these are made for doors that have a similar piece existing that can be removed and replaced, which many if not most exit doors have at the bottom.
It was very easy to remove and install the door insulation without having to remove the door, as the instructions say might be necessary. It was so easy to install, it made me wonder why I had waited.
It snapped firmly into place, and when the door is closed it seals the bottom of the door to the threshold perfectly, no light, no air.
Thinking about doing the rest of the exit doors as it is affordable, looks much better and holds the heat in during winter and the cool air in during summer
Thank you
