Do not buy this. The hole for the drain does not fit ANY of the normal garbage disposal brands (insinkerator, waste king, moen).
 1) The hole is too narrow ( I just spent an hour with diamond sandpaper scrubbing the enamel off so the drain would fit) and 
2) the sink’s hole is too deep. You cannot fasten the bottom drain piece on because of this. 
I have bought and returned too many disposals to try. Do not buy this sink.
