I have the 10-325 shower drip rail, with the black rubber seal.
However, I'd like a more pliable contact strip.
Can the clear vinyl 10-321 fit into the mounting channel on the 10-325?

You can consider using our 10-321 in the 10-325 aluminum rail. It seems to hold in, though keep in mind that it might pull out as it ages.
