Favored by law firms, this is the "“Iron Man"” of end tab file pockets. You'll appreciate our virtually indestructible file pocket that won't rip out, even when pulled from the shelf by the gusset. Gusset is fully lined with tear resistant Tyvek®, 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 pockets accommodate standard size top tab file folders to create a complete client file. This product was made using wood sourced from a certified managed forest.
