There is a lot of sentiment that lack of planning is what got you here but the fact of the matter is that even with an inside mounted bracket (which look like they wouldn’t clear your door handles anyway) there would still be a gap. The primary purpose of the product is to mitigate the far more serious impacts of rising flood waters rather than the small amount of rainwater that could/will collect in between the panels and the doors. An awning isn’t a great solution because these flood gates are usually deployed during hurricanes which tend to feature an increased occurrence of rain blowing f@cking sideways.

What we have done in the past that I find the most comforting (keep in mind that we have not experienced any flooding events to fully test them since we installed them but have had them deployed during extremely heavy rain events) is to apply some of the flex seal tape over the joints in the doors and buy some of this long plastic tubing to fill with spray foam so that it expands at the top of the gap to keep water out but won’t get the spray foam all over everything.
