The BUSINESS SOURCE BSN21904 is a set of index dividers with 15 numbered tabs and a black and white Table of Contents page, designed for organizing documents in standard three-ring binders. Each divider measures 8.5 x 11 inches and features Mylar-reinforced edges and tabs to resist tearing under regular use. The dividers are three-hole punched and ready to drop into any standard binder. Compatible with both laser and inkjet printers, they allow users to type section titles and print or copy directly onto the preprinted Table of Contents page. Instructions for setup are included in each set.
These dividers are suited for office, administrative, and school environments where document organization is a routine task. The 15-tab numbered layout supports projects, reports, reference manuals, and filing systems that require multiple clearly defined sections. The printer compatibility makes it straightforward to customize labels without handwriting. The Mylar reinforcement on tab edges extends the service life of the dividers in high-use binders.
Designed as a standard-size replacement or addition for use in three-ring binders accepting 8.5 x 11 inch dividers.
Insert dividers into any standard three-ring binder with 8.5 x 11 inch capacity. When printing on the Table of Contents page, follow the included instructions to ensure correct orientation in the printer tray. Allow printed pages to dry briefly before handling to avoid smearing.
