The BUSINESS SOURCE BSN28551 is a 1.5-inch round-ring three-ring binder built for everyday document organization in office and school environments. The back-mounted metal rings keep pages lying flat when the binder is open, reducing page curl and improving readability. A two-trigger ring mechanism allows quick, easy opening and closing without binding or jamming. The cover is constructed from polypropylene over a chipboard core, providing rigid structure and resistance to everyday wear. Exposed rivets reinforce the spine-to-cover connection for added durability. Clear interior pockets on both inside covers each hold up to 30 sheets for supplemental storage.
This binder is suited for general office filing, classroom use, and document management tasks where a reliable, low-cost solution is needed. It works well for organizing reports, reference materials, and project documents. The 1.5-inch ring capacity accommodates a standard load of letter-size sheets. Its straightforward design makes it a practical choice for bulk purchasing in office supply rooms, administrative departments, and educational settings.
Designed as a standard 1.5-inch round-ring three-ring binder compatible with letter-size hole-punched documents and standard tabbed dividers.
No tools or professional installation required. Load hole-punched documents by pressing the trigger mechanism to open the rings, insert pages, and press the rings closed until they click securely. Avoid overfilling beyond the rated ring capacity to prevent ring distortion or cover warping.
