Cabinetry is formed from 5/8" compressed wood with laminate finish with a solid fiberboard back for strength and rigidity. Strong hardboard shelves (15 lb. capacity) form fourteen basic letter-size compartments. They adjust in 2-1/2" increments to increase the size of individual compartments. Includes one 17-1/2"W x 10-1/2"D x 2-3/4"H drawer for storage of writing implements and small office supplies. Black plastic molding complements finish while doubling as a convenient labeling area (labels are included). Available in Gray and Oak. Quick and easy assembly.
