The Smead Tuff Pocket Heavyweight File Pocket is designed for durability and longevity, making it virtually indestructible while maintaining the appearance of standard redrope files. These pockets can withstand heavy loads, including large files, catalogs, or notebooks, thanks to their 6-1/2" high sides and bottoms lined with tear-resistant Tyvek. The heavyweight construction features 7/8" front and back panels for rigid support, along with a hidden reinforcement strip at the point of greatest stress. Ideal for both office and home organization needs.
