Heavy-duty file pockets are great for organizing your largest, bulkiest files and offer an alternative for limited drawer space. Gussets expand up to 3-1/2" to hold 800 legal-size sheets for your project needs. Heavyweight, 24 point front and back covers are extremely durable. Fully lined, Tyvek-reinforced gussets with added rollover feature deliver wear-resistance and tear-resistance. Extra Tyvek-reinforcement inside the covers protect against tearing. Full-length tab on back cover provides room for labels or handwritten titles. Front flap folds down for easy access.
