Thank you for your inquiry. The drain assembly is not compatible with a garbage disposal. You would need to use a garbage disposal drain. We would suggest that you contact the manufacturer of the garbage disposal for the drain that is compatible with the model you have.
Unfortunately we do not have replacement parts for the strainers.
