The OEM Smead TUFF Pocket End Tab File Pocket is designed for durability and longevity. Made from tear-resistant Tyvek, the gusset won't rip out even when pulled from the shelf. It features special rollover reinforcement at the top and extends into the front and back panels for added strength. The heavyweight front and back panels provide rigid support, while the extra wide design accommodates standard-size top-tab file folders, making it ideal for organizing client files.
