Q:Does this come as just the flange & basket strainer……or is it with the entire apparatus that attaches under the sink, to the drain?

A:  Hi Mine, The image you provided is just the sink waste flange that BLANCO sells; this is the item we offer to be installed with a garbage disposal.

    Q:Confusing. Is this the product I need? I want the basket & the flange (or whatever it's called) that has a female threaded end at bottom so I can insert the drain pipe and the locking nut on the end of the flange bottom, or whatever it's called. Thanks.

    Product was the correct color, however they were a different shade and did not match well.

    Flange won't hold the Retainer Ring in place.
    Tried mounting an Am Std ASD-1250 disposer to the flange but failed. It was impossible to tighten up the Upper Mount Ring to the flange. Each time I tried, the Retainer Ring would pop off. The diameter of the groove in the flange is simply too small. This flange proved to be a complete waste of money. And I wasted a huge amount of time trying to get it to work. Better to buy the InSinkErator version instead.

      Doesn't fit.
      Supposedly designed to work with Insinkerator disposal. It isn't. It is too small to fit on the disposal. Have to return it.
        Leaked and food got trapped underneath, removed. Not using.
