## Long description

Plastic binding spines by office products in black, designed for A4 documents with a 51 mm diameter. Each spine is intended for use with comb binding machines to secure punched pages and form booklets, reports, manuals or presentations. The pack contains 50 pieces and is suitable for assembling documents that require binding for office, school or archival purposes.
Advantages
These binding spines provide a simple and repeatable method to bind large documents up to 510 sheets. Their 51 mm diameter accommodates thick stacks while maintaining an even alignment of pages. Made from flexible plastic, the spines allow the bound document to open flat and resist minor handling damage. The consistent size and shape ensure compatibility with standard comb binding machines and make bulk binding tasks efficient.
Suitable for
Thick reports, manuals and reference documents
Technical documentation and training materials
Office and administrative packet assembly
School projects and academic submissions
Document archiving and long-term storage
Key specifications
Format compatibility: A4 documents
Spine diameter: 51 mm (suitable for up to approximately 510 sheets depending on paper weight)
Material: flexible plastic
Color: black
Quantity in pack: 50 pieces
Intended binding type: comb/spiral spine for comb binding machines
How to use
Punch the document pages with the appropriate comb-binding punch to create evenly spaced rectangular or round holes along the binding edge. Align the punched stack on the open comb spine mounted on a comb binding machine, then rotate or close the comb to engage all holes and secure the pages. After closing, verify that the spine teeth pass through each hole and that pages turn freely. For very thick stacks, split the document into sections, bind each section, then nest sections onto a single spine if needed.
Usage recommendations
Use paper weights consistently when estimating sheet capacity; typical capacity estimates assume standard 80 g/m² paper. Store spines flat in a dry environment to avoid deformation and check machine alignment regularly to prevent mispunching or uneven binding.
