The slats on the sink covers is supposed to be for plates. I use a small dish rack.
Do you know if your sink is made by Duro Form plastics? If they are you can order from them directly. All you need is the model # for the sink. It is located on the underneath backside of the sink. I ordered directly from them in 2011. It was $10 for the small side and $15 for the large side plus shipping.
Hope this helps.
