Heavy-duty D-ring binder

The Business Source 33120 is a heavy-duty D-ring binder built for high-capacity filing. It uses a chipboard polypropylene cover in red and includes a label holder on the spine. The 4-inch ring diameter holds a large volume of punched documents. Sold as a single unit.

Suits high-volume filing; not for light use

This binder suits offices, schools or archives that need to store thick reference sets securely. The D-ring design keeps pages flat and aligned. Buyers who only need a slim binder for a few dozen sheets should look at smaller capacities. It is not designed for non-punched media or ringless binding systems.

4-inch ring capacity

The defining specification is the 4-inch D-ring capacity, which determines how many sheets the binder can hold. Match this measurement to your document volume before purchasing. The chipboard polypropylene finish and integrated label holder support the same heavy-duty filing purpose.

Questions about this item

How can I confirm the D-ring mechanism on this 33120 binder is aligned properly after loading it?

Open and close the rings several times; they should snap shut with a firm click and the two halves must meet evenly without gaps.

What comes with the 33120 binder and what is not included?

The box contains the red 4-inch D-ring binder with a built-in label holder; sheet protectors, dividers and paper are sold separately.

Which capacity of the Business Source 33120 should I choose for a large archive project?

The 4-inch spine holds the most sheets in this model line, making it the right choice for high-volume filing.
