Extra-capacity hanging folder features a 2" pressboard bottom to hold larger amounts of documents such as books, binders and bulky files. Reinforced steel rods with coated tips ensure the folder can carry heavy loads of files while still sliding easily on file drawers. The lighter color on the inside helps you avoid accidental misfiling of paper between folders. Acid-free material prevents yellowing over time for long-lasting organization. Hanging folder is designed to hold letter-size documents.
