This 11 cup capacity clear Lexan work bowl only works with the more contemporary DLC-2011 Cuisinart Food Processor model with flat buttons across the front. This bowl will have a white handle and a white piece of plastic embedded in the top of the handle. This bowl belongs to the 2011 that you can take off the lid (#943238) and the expanded sleeve (#943246) at the same time. If you have to take off the sleeve first and then the handle, then you need the #943239 DLC2011 work bowl.
