Wall Hanging Mounted Plate Holders

I received a comment asking about wall hanging plate holders, but I found myself a bit confused as to what this refers to. There are holders made to display decorative plates, but there are also plate holders that are more like racks for the kitchen. Like dish racks, but mounted on the wall. In any case, either one can be purchased at Amazon and other online stores. Just use the appropriate terms when searching.
