What type of garage door seal is this

garage-doorinsulationseal

Is this a type I cannot find, or is this just a normal flat rubber type that has been shoved into the kerf cut, folded over, and stapled?

If the latter is the case, any idea why someone would do it this way, or is this common?

It's a bit hard to tell what I'm looking at from that one photo, but it may have been someone's attempt at a homemade version of the common commercial weather seal that you see on modern overhead doors.

I'd probably remove it entirely and start fresh. 3 pieces of vinyl molding with rubber gasket will probably cost under $25.
