Weatherstripping

This is weatherstripping from a French door, from the stationary side.
The house is about 30 years old and it's a 96 inch door.

The bubble measures 1/2 inch or 5/8 of an inch. I suspect it started out as 5/8 of an inch. Even if the bubble was three quarters, that would be fine.

The width of the base is 1/4 inch.

There is a small extension piece from the bottom of the bubble to the base and that measures about 1/8 of an inch.

I prefer the color black, but if it only comes in brown, that's fine too.

Thank you in advance
