This genuine KitchenAid spare part. It comes in a box from Whirlpool, the owner of KitchenAid. I purchased this from another seller and by the time it arrived I found my missing piece and no longer needed the replacement. The device I know it fits is for the 5KMSMMGA but please Google W11614119 (part number of this spare part) to see if it fits your food grinder.
