Catalina Flat Cabinet Fillers — 3 Inches Wide
Use a 3-inch-wide Catalina filler to finish the planned space between Catalina cabinetry and an adjoining wall or cabinet. Choose the height and finish that suit your layout, allowing the clearance needed for doors, drawers, handles, and nearby appliances.
Images are representative of the filler profile and finish. Refer to the selected size and dimensions below.
Sizes and manufacturer models
F330: 3 inches wide × 30 inches high × 3/4 inch thick.
F342: 3 inches wide × 42 inches high × 3/4 inch thick.
F396: 3 inches wide × 96 inches high × 3/4 inch thick.
Catalina states that these fillers can be cut to length. Verify your opening and finished height before cutting. Each selection is sold as one filler; these are flat fillers without the integrated toe-kick profile of the separate base filler.
Finish availability by height
All three heights are offered in Polar White, Shell White, Pebble Gray, Slate, Espresso, Sandstone, and Unfinished. Sage Green and Nautical Blue are offered only in the 30-inch height. The 42- and 96-inch fillers are not offered in those two accent colors.
Planning references and matching trim
Compare 6-inch fillers and base fillers with toe kick. For corner layouts, review the filler requirements on the Catalina blind-corner wall cabinet. Browse the Catalina collection or contact MDI for layout help.
