Q: Is there a a particular zipper stop you can use on this for a jacket you want to separate at the bottom?

No, these zippers don't open at the bottom.

Q: Does this have a zipper stop on it?

There are no zipper stops. This zipper comes by yards with the zipper heads installed. You separate the head from the others and cut the length you want. You have to make the zipper stops as part of the installation. However, this is easy as the zipper is plastic and you can sew over it.
