This is one of the more interesting types of shelf space designed for use in the kitchen. Many kitchens end up with, or can be purposely designed to take advantage of small spaces between cabinets. The base cabinet filler is actually an easy access narrow pullout system with three adjustable shelves. The seemingly narrow shelves with chrome rails actually hold quite a number of items, making it perfect for storing a wide variety of bottles, small boxes and the like for utilizing space that is otherwise not being used. The Rev-A-Shelf 432-BF-6C 6" Pull-Out Base Filler meets a need that many home owners never dreamed they had. The simple design, variable sizes and high quality materials make this one of the best ideas we've seen in a long time. Physical specifications: 6" W x 23" D x 30" H. Note: Fillers can only be installed with new cabinet construction.
