Product Information

Full details

The Concord 10-Part A3 Subject Dividers are designed for students, office professionals, and project managers who require a robust solution for organizing large-format documents in A3 upright binders. These dividers provide the benefit of immediate document categorization through a durable 230 micron board construction that resists tearing during frequent page-turning; however, users should note that they are specifically sized for portrait-oriented binders and may not fit landscape-specific filing systems.

Extended Product Information

FAQs

Can these be used in an A4 binder?

No, these are specifically manufactured for A3 sized paper and will be too large for a standard A4 binder.

Are the tabs reinforced?

The tabs are made from the same high-quality 230 micron board as the divider body, providing significant natural strength.

Can I use these for a landscape binder?

These are designed for A3 upright (portrait) binders; using them in landscape binders may cause the tabs to be positioned incorrectly or stick out beyond the binder cover.

How many sheets can fit behind each divider?

The capacity is limited only by the size of your binder's rings, not by the dividers themselves.

What is the thickness of the board?

The board is 230 microns thick, which is heavier and more durable than standard office divider paper.

Do these come with an index sheet?

These dividers are provided as a 10-part set with blank, customizable tabs.

Troubleshooting

Dividers do not align with binder rings

Confirm your binder is an A3 portrait (upright) model. If the binder is a non-standard or small-format ring type, the hole spacing may not match the international standard used by these dividers.

Tabs are difficult to read

Use a bold, dark felt-tip pen for labeling. If you prefer a uniform look, print small self-adhesive labels and apply them to the blank tabs rather than handwriting.

Pros and Cons

Pros

  • High-grade 230 micron board offers superior durability compared to standard paper dividers
  • Standardized 4-hole punching ensures immediate compatibility with most professional A3 binders
  • Staggered tab layout significantly reduces time spent searching for specific document sections
  • Blank tabs provide maximum flexibility for project-specific naming conventions

Cons

  • Exclusively designed for A3 portrait format; not suitable for A4 or landscape configurations
  • Tabs are manually labeled, which may not look as professional as pre-printed versions
  • Lack of a reinforced Mylar tab coating means the paper edges may soften over many years of heavy use

Setup, Compatibility & Care

To set up these dividers, align the 4-hole punched spine with the rings of your A3 portrait binder. Ensure the rings are fully open before threading the dividers to avoid tearing the paper holes. For the best result, use a fine-tip permanent marker to label the blank tabs before inserting documents into the binder; this prevents accidental smudging of the labels while the binder is closed. To care for your dividers, avoid exposure to moisture, as they are made of thick card stock, and store the binders in a cool, dry environment to maintain the board's stiffness over time.
