DURABLE Index A4+ 1-10 with Coloured Tabs and Transparent Cover Sheet
10 parts 1-10A4+ extra widthPP 270 µmUniversal punching
The DURABLE 679527 is a 10-part numbered index (1-10) in A4+ format with coloured printed tabs and a transparent cover sheet, made from tear-resistant 270 µm polypropylene — for dividing contracts, project files, HR or client folders into ten clear sections.
The A4+ size (245 x 305 mm) is deliberately wider than A4, so the tabs still stand out when your documents are stored in punched pockets. Universal punching fits all ring binders and lever arch files. A contents sheet behind the transparent cover lets you write or print what each number contains; DURABLE offers its DURAPRINT software for printing that sheet.
Before you order: This is a numbered index (1-10), not a blank tab or A-Z index. It is A4+ — it will stick out of standard A4 box files or A4-only pockets.
What's in the Box
- 1 DURABLE index set A4+: 10 polypropylene dividers with coloured printed tabs 1-10
- Index (contents) sheet
- Transparent PP cover sheet
What It Means in Practice
- Ten numbered sections — enough for a typical project, tender or personnel file.
- Tabs stay visible past punched pockets thanks to the A4+ width.
- The contents sheet under the transparent cover can be replaced and reprinted when the file changes.
- 270 µm PP does not tear at the holes as quickly as card dividers and wipes clean.
- Universal punching: fits 2-ring, 4-ring and lever arch mechanisms.
What Will Not Work
- Standard A4 box files and A4-only shelves where the extra width matters.
- Alphabetical (A-Z) or monthly filing — this set is numbered 1-10.
- More than 10 sections — choose a larger numbered set.
- Writing directly on the tabs — the numbers are printed; labelling is done on the contents sheet.

Frequently Asked Questions
Will it fit my lever arch file?
Yes — DURABLE specifies universal punching for all lever arch files and ring binders.
Why A4+ instead of A4?
The extra width keeps the tabs visible when documents are in punched pockets, which are wider than the paper.
Can I print the contents page?
Yes. The contents sheet is replaceable and DURABLE offers DURAPRINT software to print it.
Singular Expert Insight · Buyer's Guide
Numbered 1-10 indexes are the standard for structured files that follow a fixed outline — tenders, contracts, technical documentation. If you file in punched pockets, A4+ is the right choice; if not, a plain A4 index keeps the file flush. Browse our
stationery range for ring binders, pockets and other filing products.
✓ Buy it if you organise binders into numbered sections and use punched pockets.
✕ Skip it if you need A-Z or monthly tabs, or your files must stay strictly A4 wide.
→ Also consider DURABLE numbered indexes in other section counts and A-Z indexes.
