1-1/2" Slant D-Ring Binder

The Business Source BSN33125 is a slanted D-ring binder designed for professionals who manage large document sets. Its back-mounted rings allow pages to lie completely flat during reference or copying. The spine label holder supports quick identification on crowded shelves.

Capacity and headroom

The 1-1/2" rings hold up to 375 sheets of paper, and the slant D-ring design fits up to 25% more sheets than same-size round rings. This capacity suits training manuals, reports and presentations that exceed the limits of standard round-ring binders. Very high-volume archives may require multiple binders or a larger ring diameter.

Build quality and daily use

No-gap rings stay tightly closed without gaps, keeping contents secure during transport. A utility pocket inside the front cover stores loose pages or dividers, while double opening and closing boosters make repeated access smooth. The durable black cover protects documents in daily office environments.

Questions about this item

Will the 1-1/2" slant D-rings in the BSN33125 binder hold my existing archive of 375 sheets without forcing them?

The 1-1/2" back-mounted slant D-rings are rated for up to 375 sheets and designed to hold 25% more paper than same-size round rings, so a 375-sheet archive fits at the rated capacity.

How can I confirm the BSN33125 binder's no-gap rings are closing properly after I load it?

Check that the back-mounted rings snap shut with no visible gap between the halves and that pages lie flat when the binder is opened, which confirms the double boosters are functioning.

Does the BSN33125 binder come with index dividers or sheet protectors, or do I need to buy those separately?

The box includes the binder only, featuring a utility pocket inside the front cover and a spine label holder; dividers and sheet protectors are sold separately.
