Business Source 33121 Slant D-Ring Binder 5" Black

High-capacity slant D-ring binder

The Business Source 33121 binder uses slant D-rings mounted on the back cover so pages lie flat and hold up to 25 percent more paper than same-size round rings. A no-gap design keeps rings tightly closed without gaps for secure document retention. Polypropylene covering over sturdy chipboard provides durability while a non-glare CleanView surface resists toner transfer from printed pages. A label holder on the spine allows quick identification of contents.

Suits high-volume filing and frequent reference

This binder suits offices and students who need maximum sheet capacity in a single three-ring binder and want pages to stay flat during reading or copying. The interior utility pocket and two clear pockets add extra storage for loose sheets or indexes. Buyers who need a smaller ring size, a different ring style, or multiple binders in one pack should look at other options because this model is sold as one each with a 5-inch slant D-ring configuration.

Check ring size and storage needs before ordering

Verify that a 5-inch slant D-ring capacity matches the volume of paper you plan to store so the binder is neither overfilled nor underused. Confirm that back-mounted rings and the lay-flat design fit your workflow for copying, scanning or frequent page turning. Ensure the single-unit quantity meets your requirement, as this product is not sold in multi-packs.
