18pt End Tab Classification Folders, 3-Dividers, Letter Size, Yellow, 10/Box

These yellow letter size end tab classification folders with 3 dividers are designed for shelf filing systems that need expanded capacity, multiple document sections, secure fasteners, and easy-to-read end tab labeling. They are a practical choice for medical charts, legal files, personnel records, insurance files, office records, and other high-volume filing applications.

This version is made with 18 pt yellow folder stock and includes three 18 pt manila dividers. It should be sold separately from heavier 25 pt pressboard classification folders, because this folder offers a lighter 18 pt construction while still providing multiple filing sections, end tab visibility, and fastener-based document organization.

Each folder includes a 3″ gray Tyvek® reinforced expansion, giving the file extra room to grow while helping protect the gusset from tearing and everyday wear. The end tab design works well in open-shelf filing systems and lateral file cabinets where folders are accessed from the side and labels need to remain visible.

For secure document storage, each folder includes two 2″ bonded fasteners on the inside front and inside back, plus 1″ duo fasteners on the manila dividers. This creates multiple filing surfaces for separating documents by section, date, document type, department, case stage, or workflow step.

18 pt vs. 25 pt Classification Folders

This folder is an 18 pt end tab classification folder, not a 25 pt pressboard classification folder. The 18 pt construction is a lighter option for filing systems that still need multiple dividers, internal fasteners, and a larger 3″ expansion, but do not require the added stiffness of heavier 25 pt pressboard.

Choose this version when you want a functional divided classification folder with lower bulk, lighter folder stock, and extra file capacity. Choose a 25 pt pressboard version when maximum rigidity and heavy-duty long-term file handling are more important.
