The Smead TUFF Pocket Heavyweight Super Tuff File Pocket is designed for durability and longevity, making it virtually indestructible while maintaining the appearance of standard redrope files. These file pockets can withstand heavy loads, accommodating large files, catalogs, or notebooks with ease. They feature 6-1/2" high sides and bottoms lined with tear-resistant Tyvek, and the tops are reinforced with a special rollover design. With heavyweight 7/8" front and back panels, these pockets provide rigid support and include a hidden reinforcement strip at the point of greatest stress.
