The BUSINESS SOURCE BSN28556 is a 1-inch capacity round-ring binder designed for everyday document organization in office and school environments. Built with a polypropylene cover over a chipboard core, it provides a firm, lightweight structure that holds up under regular use. Two trigger rings make opening and closing quick and straightforward, reducing wear on documents during repeated access. Back-mounted metal rings allow pages to lie flat, which matters when reading or writing in an open binder. Clear interior pockets on both the front and back covers each hold up to 30 sheets of additional loose material.
This binder suits general office filing, report assembly, student use, and light archival tasks. It works well in environments where a cost-effective, functional binding solution is needed without additional features. The exposed rivet construction at the ring mechanism adds structural durability for day-to-day handling. It is sold individually and is suitable for standard 8.5-inch by 11-inch three-hole-punched documents.
Designed as a standard replacement or supplemental binder for use with 8.5-inch by 11-inch three-hole-punched documents in residential, school, or general office settings.
No installation is required for this product. Insert three-hole-punched documents by pressing the trigger rings to open and releasing to close. Avoid overfilling beyond the rated 1-inch capacity, as doing so can stress the ring mechanism and cause misalignment over time.
