Durable A4 Numbered Index 1–52 — 52 embossed PP tabs in grey
52 tabs · 1–26 + 27–52A4 portraitPolypropyleneUniversal punching
The Durable 650410 is an A4 numbered index with 52 tabs, numbered 1–52 in two sequences (1–26 and 27–52), made of grey polypropylene with embossed numbers — for anyone who files contracts, client records, invoices or weekly paperwork in a ring binder or lever arch file and wants each section easy to find.
Because the numbering is split into two runs of 26, the set can be used as one 52-section index (for example one tab per week of the year) or divided between two binders. Polypropylene does not tear at the punched holes the way card dividers do, and the embossed numbers do not rub off with handling.
Before you order: The index sheets are 230 mm wide including the 15 mm tabs. In a binder full of punched pockets that are also 230 mm wide (standard for many A4 pockets), the tabs will sit level with the pockets and be hard to see — use an extra-wide index in that case.
What's in the Box
- 1 × Durable A4 numbered index, 52 parts (1–26 and 27–52), grey polypropylene
- No binder, pockets or cover sheet are included
What It Means in Practice
- 52 tabs = one per week of the year, or one per client, project or account number in a long-running file.
- Two sequences (1–26, 27–52) make it easy to split one year across two binders or to separate two halves of an archive.
- Universal punching fits standard 2-hole and 4-hole A4 ring binders and lever arch files.
- Polypropylene is moisture-resistant and wipe-clean, so it suits workshops, warehouses and frequently handled files.
What Will Not Work
- It is numeric only — there are no A–Z letters, months or blank write-on tabs; buy an alphabetical or month index if that is how you file.
- No contents/cover sheet is listed by Durable for this set, so you will need to keep your own list of what each number stands for.
- It is not an extra-wide index (see the note above), and it is not made for A5 or US Letter binders.

Frequently Asked Questions
Is this one index or a pack of five?
Durable's product data sheet lists a sales unit of 1 piece: one 52-part numbered index. If you need several sets for a team, tell us the quantity and we will quote.
Will it fit my lever arch file?
Yes — the sheets have universal punching for standard A4 ring binders and lever arch files. For non-standard binders send us the model and we will check.
Can I label the tabs with names?
The tabs carry embossed numbers only. Most users keep a separate contents list at the front of the binder mapping each number to a client, week or project.
Singular Expert Insight · Buyer's Guide
Numbered indexes are the most flexible way to organise a long-running file, because the numbers can mean anything: weeks, accounts, rooms or projects. The one detail that catches buyers out is width — at 230 mm this is a standard-width index, so it works best in binders filled with loose punched paper rather than full-width pockets.

stationery range.
✓ Buy it if you file by number, week or account and want durable PP tabs that survive years of handling.
✕ Skip it if you file alphabetically or by month, or your binder is full of 230 mm punched pockets.
→ Also consider Durable 267219 A4 punched pockets for unpunched documents in the same binder.
