File pockets won’t rip out even when pulled from the shelf by the gusset. Gusset is fully lined with tear-resistant material. Pocket expands 3-1/2″. It also has special rollover reinforcement at the top and extends into the front and back panels twice as far as standard file pockets. Super-heavyweight, front and back panels provide rigid support and have a hidden reinforcement strip at the point of greatest stress. Extra-wide design accommodates standard-size, top-tab file folders to create a complete client file. Letter-size file pockets have end tabs and are made of redrope stock.
