The BUSINESS SOURCE BSN45100 is a 1-inch round-ring view binder designed to hold 11x17 inch tabloid-size documents. Back-mounted rings allow pages to lie flat during use, reducing the interference that front-mounted rings create when writing or reading. A clear overlay on the front, back, and spine accepts insert sheets for easy title customization without labels or tape. This binder suits office professionals, project managers, and administrative staff who work regularly with oversized documents and need a durable, everyday organizer.
This binder is intended for use with 11x17 inch tabloid documents, making it a practical choice for engineering drawings, architectural plans, legal exhibits, financial spreadsheets, and other oversized materials. It fits standard applications in office environments, project documentation workflows, and active filing situations where flat page storage improves readability and handling. The unit of measure is each, and the minimum order quantity is 1.
Designed as an OEM-style replacement and standard option for use with 11x17 inch tabloid documents in round-ring binder applications.
No tools are required to load or set up this binder. Insert a printed or handwritten title sheet under the clear overlay on the front, spine, and back before first use. When loading documents, open the rings fully before inserting pages to avoid stress on the ring mechanism. Store the binder upright on a shelf to maintain ring alignment over time.
