Binding Combs office products A4 28.5 mm (holds 270 sheets), pack of 50, blue

Plastic binding combs by office products for A4 documents with a 28.5 mm diameter, designed to bind up to 270 sheets. The pack contains 50 blue combs suitable for use with manual or electric comb-binding machines that accept A4 comb spines. These combs provide a refillable and durable binding solution for booklets, reports, manuals and presentations where easy page addition or removal is required.

Advantages

Blue plastic combs are lightweight, resilient and resistant to everyday wear. The standard 28.5 mm diameter accommodates thick sets of documents while maintaining an even spine that lies flat on a desk. The combs are compatible with most comb-binding machines designed for A4 format, enabling quick assembly and future editing of bound documents without damaging pages.

Suitable for

• Training manuals and course materials
• Project documentation and proposals
• Catalogues, price lists and booklets
• Any multi-page documents requiring refillable binding

How to use

Open the comb by placing it on a compatible comb-binding machine and activating the opening mechanism, or manually spread the rings if the comb design allows. Align punched document holes with the open comb rings and insert pages gradually to ensure even distribution. Close the comb firmly so that the rings return to the closed position and secure the pages. After binding, the comb allows easy removal and reinsertion of pages for updates or reordering.

Usage recommendations

For best results use standard punched holes spaced for A4 comb-binding machines and standard office paper (80 g/m²). To achieve a neat spine and consistent document thickness, avoid overfilling beyond the recommended sheet capacity and check machine compatibility with 28.5 mm combs before use.
