I'm trying to come up with a solution to close a gap underneath a metal roll
up door. The door has a rubber seal at the bottom but the concrete
finishers did not do a good job at forming a straight slope at the entrance.
The middle of this area in the floor is kinda low in the middle creating
about a 1 inch gap throughout about 60 percent the length of the door. The
ends of the door towards the guides are fine.
I was thinking about slicing in half some pipe insulation foam and glueing
to the rubber seal to close the gap...
Anyone have any better ideas ??
It may have for you, but the OP said he had a 1" gap over part of the
span and the thing you pointed him to is only a half inch high. It
couldn't work even if it could squish down to almost nothing.
If your bottom seal can be replaced for a larger type which can seal on your
floor. You can also replace the seal retainer for the type that wraps
around the bottom of the door, mounted at an angle it can thoroughly seal
