Hi this is Barbara Olsen I had ordered the sink from you or maybe a month Ago and I have a question about a C. Grad that sits in the bottom I Don\'t believe 1 came with the sink or is available it\'s that whole layer ... report I can\'t remember anyway ... it\'s a 300 model and it\'s interior dimension is 16 5 28 I think anyway I was wondering if you could recommend the same grid if since it doesn\'t come with 1 I\'ve seen some online at other locations that might work and I wanna know if you can\'t provide me with the name what tolerance ... what I need a half inch either side or a full and she their side or just ... maybe a quarter inch I Don\'t know so my number is (515) 298-2143 thank you bye bye
