Unique file pocket design has a raised gusset height so that the gussets ride along the file cabinet rails. This eliminates tearing and damage caused by removing file pockets with low gussets. 9.5 in high gussets are reinforced with rip-proof strips with Dupont Tyvek material along the top and bottom corners. Extra-thick, 22 pt. outer panels for added durability. Box of 10. Brown. 100% recycled, 30% post-consumer content.
