Spiral Binding Coil Nenurodyta 405281/100 28.5 mm White for document binding

Spiral binding coil Nenurodyta 405281/100 28.5 mm White is a pre-formed white plastic coil designed for binding multi-page documents. With a nominal diameter of 28.5 mm, this coil provides adequate capacity for medium-thickness documents such as reports, manuals and presentations. The flexible spiral allows pages to turn smoothly and the white finish creates a clean, professional appearance suitable for office, school or print-shop use.

Advantages

This white spiral coil offers secure page retention while allowing full 360-degree page rotation for easy reading and copying. The plastic construction resists crushing and maintains shape during handling and storage. Its nominal 28.5 mm diameter gives predictable capacity for consistent, neat binding results when used with compatible punching and inserting equipment or manual insertion methods.

Suitable for

• Binding reports, manuals and booklets
• Office and school documents
• Presentations and training materials
• Small print-shop and reprographic jobs

Key specifications

• Coil type: pre-formed plastic spiral
• Nominal diameter: 28.5 mm
• Color: white
• Designed capacity: medium-thickness documents (approx. compatible with ~200–250 sheets depending on paper thickness)
• Usability: compatible with binding machines and manual systems that accept 28.5 mm coils
• Finish: smooth, rounded spiral for easy page turning

How to use

Align punched document pages and insert the spiral coil through the punched holes by feeding one end of the coil through the holes and rotating or threading along the document edge until the coil passes through all sheets. If using a coil insertion machine, secure the document in the machine and follow the device instructions for feeding the coil. After insertion, trim excess coil length if necessary and crimp or apply end stops if required by the binding system to prevent uncoiling.

Usage recommendations

For best results, match the coil diameter to the total document thickness and ensure punched holes are compatible with spiral pitch. Store coils flat in a dry environment to prevent deformation and handle finished documents gently to maintain coil shape and page alignment.
