The BUSINESS SOURCE BSN28561 is an economy-grade, left-hand round ring binder designed for everyday document storage and organization in office and school environments. Built with a black polypropylene cover over a sturdy chipboard core, this binder holds standard 8.5 by 11 inch documents with 2-inch round metal rings mounted to the back panel. Back-mounted rings allow pages to lie flat for easier reading and writing. Two trigger mechanisms provide quick, controlled ring opening and closing. Inside cover pockets are clear and hold up to 30 sheets each, adding convenient front and back storage for loose pages or reference materials.
This binder is suited for general office filing, student use, and light-duty professional applications. The left-hand design positions the ring mechanism on the back cover, which keeps pages flat and reduces interference when writing directly in the binder. Exposed rivets reinforce the ring mechanism attachment, contributing to longer service life under regular use. A label holder on the spine allows for quick identification on shelves or in file cabinets without removing the binder. Ideal for organizing reports, meeting materials, project documents, or academic coursework.
Designed as a standard replacement or addition for general-purpose round ring binder applications using 8.5 by 11 inch documents in office, school, or light commercial settings.
No tools or trade installation required. Insert documents by pressing the two triggers simultaneously to open the rings, load pages onto the rings, and release to close. Ensure rings are fully closed and aligned before shelving to prevent page damage. Store upright on a flat surface or shelf for best long-term performance.
