Binding Spines OFFICE PRODUCTS A4 22 mm (binds 210 sheets) 50 pcs blue

Office Products A4 binding spines, 22 mm diameter, are designed to bind documents up to approximately 210 sheets. Each pack contains 50 blue plastic comb spines compatible with most manual and electric comb-binding machines that accept A4 comb bindings. These spines provide a secure and professional finish for reports, manuals, presentations and archived documents where a medium-thickness binding is required.

Advantages

A 22 mm diameter offers a balance between capacity and compactness, suitable for medium-sized documents without adding excessive bulk. The blue colour provides a consistent, identifiable appearance for filing systems and team documents. The plastic material is durable, resistant to bending and suitable for repeated handling.

How to use

Punch the document sheets and cover using a compatible comb-binding machine set for A4 punching. Align the punched stack with the open comb spine, spread the comb rings and insert the spine through the punched holes until the document is seated evenly. Close the comb using the machine or manually if applicable to secure the pages. Check alignment and page order before final closure to ensure an even, professional result.

Usage recommendations

For best results, use covers or heavier-weight first and last pages to protect the document and improve durability. Choose a 22 mm spine when the final document thickness is near 200 sheets; reduce diameter for slimmer sets or increase diameter for larger compilations. Store spines flat in a dry environment to prevent deformation.
