The BUSINESS SOURCE BSN01807 is a set of monthly index dividers designed for organizing documents in standard three-ring binders. Each divider features a plastic tab extending 0.375 inches, clear-coated on both sides for durability and easy readability. The divider body is made from heavy-duty buff-colored paper with a reinforced binding edge to resist tearing at the punch holes. Three punched holes sized at 0.28125 inches accommodate standard binder rings. Tabs are pre-labeled January through December, providing a ready-to-use monthly filing system for office and administrative applications.
These dividers are suited for residential and commercial office environments where document organization by month is required. Common applications include filing systems for invoices, reports, service records, and correspondence. The 8.5 by 11 inch size fits standard letter-size binders. Office administrators, records managers, and field technicians maintaining service documentation will find these dividers a practical organizational tool.
Designed as a standard replacement or supply item for three-ring binders accepting letter-size 8.5 by 11 inch dividers with a three-hole punch pattern.
Insert dividers into any standard three-ring binder by opening the rings and aligning the pre-punched holes with the binder mechanism. No tools are required. Ensure rings are fully closed after insertion to prevent divider movement during use.
