Binding Combs office products A4 16 mm (up to 145 sheets) — 100 pcs, black

Plastic binding combs office products A4 16 mm (up to 145 sheets) — 100 pcs, black are flexible comb spines designed for comb binding A4 documents. Each comb has a 16 mm diameter spine that accommodates up to 145 sheets of standard 80 g/m² paper when punched with a compatible 21- or 34-hole comb binding machine. Supplied in a pack of 100 pieces in black, these combs provide a reusable binding solution for reports, manuals, presentations and other multi-page documents. The plastic construction allows the comb to open and close repeatedly so pages can be added or removed without damaging the spine or the document.

Advantages

These binding combs offer straightforward installation and repeated reusability, enabling quick assembly and later modification of bound documents. The durable plastic resists cracking and keeps the spine shape under normal handling, ensuring pages turn smoothly. A neutral black finish provides a professional appearance suitable for business, education, and home office use. The pack quantity of 100 supports wide use across offices or print environments with moderate binding needs.

How to use

Punch the document pages and cover using a compatible comb binding machine set for A4 punch configuration. Open a comb by placing it on the machine’s comb opener and rotating to spread the fingers. Thread the punched edge of the document onto the opened comb fingers, then release the opener to close the comb and secure the pages. Verify that all pages turn freely and that the cover aligns correctly with the spine. To add or remove pages, reopen the comb and adjust the sequence, then close it again following the same procedure.

Usage recommendations

For reliable results, use standard 80 g/m² paper and matching covers; check that your binding machine supports the hole pattern required for comb binding. Store packs flat in a dry environment and avoid prolonged exposure to direct sunlight to preserve the plastic’s shape and colour.
