Built-in reinforced tabs are attached to the folder—no assembly required. Stronger than ordinary hanging folders are easy to label by writing directly on the tabs or by applying self-adhesive labels. Tabs are embossed for simple label placement. 11 pt. stock is glued around rods on both sides for durability. Rod tips are coated smooth gliding in file cabinets. This product was made using wood sourced from a certified managed forest.
