Building/remodeling your old kitchen? Well, all kitchens are not the same size and sometimes you are left with extra space that you hate to go wasted. Look no further and waste no more. Rev-A-Shelf® has created a filler that takes previously wasted and unusable space and creates a functional organizer. Fillers are intended to be installed in-between (2) cabinets in new kitchen construction/remodel job and will not work in existing kitchen cabinets. Fillers are available for your wall and base cabinets and also come in 3”, 6” and 9” widths and various heights (for wall cabinets). It is always good to consult with your kitchen designer to see if you have the space to add a filler.
