Using Rev A Shelf Products With Inset Doors
Rev-A-Shelf products offer a great way to add spice racks, cookie sheet racks and other helpers to kitchen cabinets. However, they are designed for overlay style doors, not inset doors. More accuracy in closing is required for inset doors, plus you lose 3/4 of an inch in depth to the door itself. I found that Rev-A-Shelf products can work for inset applications, but there are some modifications you'll need to make.
