Look no further for one of the smartest, most innovative hanging folders around. Featuring SureHook technology-a longer, flexible hook with revolutionary built-in tension springs-these acid-free folders will work with existing systems. The rods and hooks are stronger and sturdier, so the rods bend less while folders stay on rails and slide with ease. They include clear PVC-free tabs and printer-ready inserts, with patented polylaminate reinforced tops and bottoms to provide strength, and their lighter interior helps prevent misfiles. Plus, there's a new dispenser box for quick, one-at-a-time access. This product was made with wood sourced from a certified managed forest.
