We understand that when addressing filing needs for any busy office environment, you need to have durable folders that can stand withstand heavy daily use. Our letter size, top tab classification file folders have been designed and manufactured for use with standard file cabinets and letter size hanging file folders. Constructed with thick 25 pt pressboard and durable bonded 2-prong fasteners, it's easy to repeatedly add and remove large amounts of client or employee forms, business reports, and more without risk of the reinforced prongs breaking off or tearing through the folder cardstock. The wide top tabs are ready to have labels written or applied in accordance with your office's chart organization systems, while the 2” Tyvek expansions allow for the secure organization of more than 100 sheets of paper within the same classification folder.
