90″ Microwave Appliance Tall cabinets consist of two stacked sections for easier transportation and installation. The 66″H bottom cabinet features a pair of 30″h doors with one full depth adjustable shelf, a 6″h drawer front with a 4″ drawer box and a 24.5″h appliance opening. The 24″H upper cabinet features a pair of full length doors and one full depth adjustable shelf. The appliance opening section includes two 4″ filler pieces to perfectly frame the appliance, but additional fillers can be purchased in accessories and add-ons if needed. It is recommended to have your appliance picked out and its specifications referred to prior to purchasing this cabinet. Varsa Woodworks is not responsible for incompatibility with appliance or incorrect installation. Finished Tall End Panels are recommended on visible sides to create a seamless finish between both cabinets. All Tall cabinets finish deeper than base cabinets and create a natural stopping point for counter tops.
