Binder Specifications

The Business Source 28523 is a round-ring binder with a one-inch capacity and a black vinyl finish. It uses a polypropylene cover over a chipboard core with exposed rivets for rigidity. Two triggers on the ring mechanism allow quick opening and closing, and back-mounted metal rings keep pages lying flat. Two clear inside pockets provide additional document storage.

Ideal Use Cases

This binder suits students or office workers who need a lightweight, PVC-free option for moderate document volumes. The single-ring capacity and single-unit quantity make it less practical for high-volume archiving or multi-binder filing systems. Buyers who need larger ring sizes or heavy-duty leverage arch mechanisms should look at other models.

Deciding Specification

The one-inch ring capacity is the single figure that determines whether this binder fits your filing needs. It sets the maximum thickness of paper the rings can hold, so verify your typical document stack against this measurement before purchasing.

Questions about this item

What size paper do I need for the Business Source 28523 binder?

It takes half-letter sheets measuring 8-1/2 by 5-1/2 inches.

Will my existing half-letter dividers and sheet protectors fit the three-ring mechanism?

Yes, the round rings use standard half-letter spacing so current accessories will work.

How can I confirm the rings are aligned correctly after loading pages?

Pages should lie flat when the binder is open and the two triggers should snap shut cleanly.
