DURABLE Index A4+ 1–20 — Numbered Coloured Tabs with a Printable Contents Sheet
20 Parts · 1–20A4+ Extra-WidePP 270 µmUniversal Punching
The DURABLE Index A4+ 679727 is a 20-part polypropylene file index with coloured tabs numbered 1–20 and a printable contents sheet under a transparent cover, for lever-arch files, ring binders and punched pockets in offices, accounts departments and project archives.
The A4+ size (245 × 305 mm) is wider than an A4 page, so the tabs stay visible even when documents are filed in punched pockets. The 270 µm polypropylene is tear-resistant and wipe-clean, and the contents sheet can be printed from a PC and replaced, so the index is reused when the file contents change.
Before you order: The tabs are pre-numbered 1–20 — this is not a blank-tab index. If you need to write your own words on the tabs, choose a blank-tab DURABLE index instead.
What's in the Box
- 1 × DURABLE 20-part index A4+, tabs numbered 1–20, multicoloured
- 1 × transparent cover sheet with printable contents (index) sheet
What It Means in Practice
- Universal punching fits standard 2- and 4-ring binders and lever-arch files.
- Extra width (A4+) means tabs project past punched pockets, so you can still find section 14 when every page is in a sleeve.
- Print the contents sheet from your PC (DURABLE provides templates through its DURAPRINT software) and swap it whenever the file is reorganised.
- Copy-safe polypropylene does not stick to copier-fresh prints and survives frequent handling better than paper or card dividers.
What Will Not Work
- Custom tab text: tabs are numbered 1–20 only.
- Files with more than 20 sections — use a larger DURABLE index or combine two.
- Narrow A5 binders or non-standard ring mechanisms that do not match universal punching.

Frequently Asked Questions
Does it fit a standard lever-arch file?
Yes — DURABLE specifies universal punching for lever-arch files, ring binders and punched pockets.
Can I reuse it?
Yes. Print a new contents sheet and replace it under the transparent cover; the PP tabs are made for repeated use.
Why A4+ and not A4?
The extra width keeps the tabs visible when your documents are in punched pockets, which are wider than a bare A4 sheet.
