The BUSINESS SOURCE BSN21905 is a 25-tab A-to-Z index divider set designed for organizing letter-size documents in standard three-ring binders. Each set includes tabs labeled A through Z with Mylar reinforced edges and tab tips to resist tearing under regular use. A black and white Table of Contents page is included, allowing users to key in or type section titles before printing or copying. The dividers are three-hole punched and compatible with both laser and inkjet printers, making them suitable for office, administrative, and educational filing applications.
This divider set fits letter-size binders and works across a wide range of filing and document organization tasks. The printable Table of Contents page supports customized labeling without handwriting. The Mylar reinforcement on both edges and tabs extends the service life of the dividers in high-use binders. Simple setup instructions are included in each set. Well suited for administrative professionals, office managers, and anyone maintaining organized reference binders.
Designed as an OEM-style replacement for standard letter-size three-ring binder index divider sets compatible with laser and inkjet printers.
Insert dividers into a standard three-ring binder in alphabetical order before loading documents. Print or copy the Table of Contents page using a laser or inkjet printer before inserting into the binder. Handle tabs by the reinforced edges to maintain longevity in high-use applications.
