Business Source BSN28451 5 Inch D-ring View Binder Black

Product Description

The BUSINESS SOURCE BSN28451 is a 5-inch capacity D-ring view binder designed for high-volume document organization in office and school environments. Back-mounted slant-D rings keep pages lying flat and hold approximately 25 percent more paper than standard round-ring binders of the same spine width. The covers are constructed from polypropylene over a chipboard core, providing a rigid structure that resists warping. Clear non-glare overlays on the front, back, and spine accept printed inserts for quick labeling and identification. Office administrators, records managers, and educators are the primary installers of this product.

This binder is suited for organizing printed reports, project documentation, reference materials, and archival files in both residential office and commercial workplace settings. The 5-inch spine accommodates large document sets that exceed the capacity of standard 3-inch or 4-inch binders. Two triggers on the ring mechanism allow one-handed opening and closing, reducing handling time during frequent document retrieval. Each inside cover includes a clear pocket with a 30-sheet capacity, providing supplemental storage for loose inserts or reference sheets.

Installation Notes

No tools are required for setup. Insert printed cover sheets into the clear overlay pockets before loading documents to complete labeling. When loading large document sets, open both triggers fully before inserting or removing pages to avoid stressing the ring mechanism. Store the binder upright on a shelf to maintain spine shape over time.
