The Kraus kitchen sinks have a standard drain opening. This will work with most garbage disposals in the market. Typically, with a standard sink drain like Kraus', the flange to install the disposer would be purchased with the disposer.

We have an existing garbage disposal hooked up but I am looking to remove the hook up for now but if we wanted to add it down the road again I wanted to make sure that I have all the necessary parts. Thank you.

I'm ready to install mine. Any way I can install the oem drain with the catch and a garbage disposal? or is it one or the other situation?

It is one or the other situation.
