Hanging pockets with full-height gussets are ideal for storing large amounts of paperwork. Documents remain at one height when gusset expands up to 3-1/2". Full-height side gussets keep the pocket from getting caught when trying to take them out of a drawer or box. Documents are also better protected and secured in the pocket. Great for frequently used files. Pockets are slotted in front and back inside panels to accept tabs (sold separately). Hanging pockets are made of 11 point stock.
