## Long description

Black plastic binding spines Office Products A4 38 mm are designed for comb binding A4 documents and hold up to 350 sheets. The pack contains 50 spines sized for standard A4 punch patterns and intended for use with comb binding machines in offices, print shops and reprographic centres. These spines provide a fixed, reboundable edge that keeps punched pages aligned and allows documents such as reports, manuals and presentations to open flat.
Advantages
These binding spines are made of flexible plastic that resists cracking and maintains shape after repeated opening and closing. The 38 mm diameter accommodates thick documents up to approximately 350 sheets, reducing the need to split content across multiple volumes. A standard comb profile ensures reliable engagement with punched holes, while the black finish gives a neutral, professional look suitable for business and archival documents.
Suitable for
 Binding reports, manuals and training materials

Key specifications
 Format compatibility: A4
 Spine diameter: 38 mm
 Capacity: up to 350 sheets (dependent on paper thickness)
 Material: flexible plastic comb
 Colour: black
 Pack quantity: 50 spines
 Compatibility: standard comb binding machines and A4 punch pattern
How to use
Prepare your document by punching holes along the binding edge with a comb binding punch compatible with A4 pattern. Select a 38 mm spine to match the thickness of the stacked pages. Fit the comb onto the binding machine opener, align the punched document teeth over the opened comb and close the comb to secure pages. After binding, check that pages turn freely and that the comb closes evenly along the spine.
Usage recommendations
For best results, count or measure the document thickness before selecting the 38 mm spine to ensure it fits the intended sheet count; use standard-weight paper to match the listed capacity. Store spines flat and away from direct sunlight or high heat to prevent warping. When binding frequently used manuals, consider reinforcing the cover edge with heavier card stock to reduce wear at the spine.
