## Long description

Office Products binding spines for A4 documents with a 51 mm diameter are designed to bind up to 510 sheets in a single booklet. The pack contains 50 green plastic comb spines compatible with most manual and electric comb-binding machines, allowing quick assembly of reports, presentations, manuals and other multi-page documents. These comb spines are intended for repeated office and school use where a secure, flat-bound finish is required.
Advantages
These binding spines provide a reliable and consistent method to hold large stacks of A4 paper together while allowing the finished booklet to open flat. The 51 mm diameter accommodates up to approximately 510 sheets, reducing the need for multiple volumes when compiling long documents. Made of durable plastic, the combs resist deformation under normal handling and maintain page alignment over time. Their universal design works with standard comb-binding machines, enabling both manual and automated finishing workflows.
Suitable for

Key specifications
 Format compatibility: A4 documents
 Spine diameter: 51 mm (suitable for up to ~510 sheets)
 Material: durable plastic comb
 Color: green
 Quantity in pack: 50 spines
 Compatibility: fits most manual and electric comb-binding machines
How to use
Arrange and align the A4 pages in the desired order, then puncture punch the stack using a compatible comb-binding machine according to the machine's instructions. Open a plastic comb spine on the machine's opener, place the punched pages onto the comb rings and close the comb until it secures the pages evenly. Verify that the booklet opens flat and that pages turn freely; if necessary, reopen the comb to adjust page alignment before final closure.
Usage recommendations
For consistent results, use a comb-binding machine rated for A4 punching and ensure the punched holes align with the comb rings. When binding near the capacity limit, consider reducing the sheet count slightly to avoid strain on the comb and to ensure smooth opening. Store spare spines flat in a dry environment to prevent warping.
