Binding Spines Office Products A4 45mm for 440 sheets, 50 pcs, red are plastic comb binding spines designed for A4 documents. Each spine has a 45 mm diameter and can accommodate up to approximately 440 sheets, enabling creation of thick documents such as manuals, reports and presentation booklets. The pack includes 50 red spines suitable for use with standard comb binding machines; spines provide removable, re-openable binding and allow pages to lie flat for reading and copying.

Advantages

These plastic binding spines offer consistent, evenly spaced teeth that engage securely with punched document holes, producing a professional, uniform finish. The 45 mm diameter is intended for larger document volumes and maintains page alignment while permitting smooth opening. The plastic construction is durable and resistant to deformation, while the red colour makes bound documents easy to identify and sort. Spines are compatible with most comb binding systems that support A4 format and 45 mm combs.

How to use

Prepare the document by aligning and punching holes with a compatible comb binding punch for A4 paper. Select a 45 mm comb spine and place the document onto the open comb on the binding machine. Close the comb to engage teeth into the punched holes, then rotate or press the comb closed according to the binding machine instructions to secure the pages. If disassembly is required, open the comb, remove or rearrange pages, and re-close the comb as needed. Ensure punched holes match the comb pitch for reliable engagement.

Usage recommendations

For durable results, use a compatible comb binding machine with matched punch pitch and avoid overfilling beyond the recommended sheet capacity. Store unused spines flat in a dry environment away from direct sunlight to prevent colour fading or warping. Choose red spines for visual categorization or departmental colour-coding.
