Heavy-duty file pockets are built for long-term use. Sides are taller than the rails in drawers so they won't get caught under them when the legal-size file is lifted from the drawer. Coupled with these pockets' generous expansion, this design eliminates tearing and damage. 22 point extra-thick covers are designed to work inside the file cabinets with 9-1/2" tall gussets to ride along the rails of the cabinet drawer. Full-length tab on back cover provides room for labels or handwritten titles. The gussets are extra reinforced with Tyvek strips along the top and bottom corners, and the outer panels are extra thick for added durability. Top straight-cut tab makes it easy to identify in the file cabinet.
