Ring binder Hamelin Elba 100400554 A4+ polypropylene 50 mm spine grey

Hamelin Elba 100400554 A4+ ring binder is a polypropylene (PP) document binder designed for storing and presenting punched papers, reports and presentations. With outer dimensions of 320 × 285 mm and a 50 mm spine, the binder accommodates large A4+ documents and holds a substantial volume of sheets while maintaining a compact, professional appearance. The product uses double PP foil on the base for extra protection and incorporates an internal stabilising system for reliable standing stability.

Advantages

The binder features a precise and durable ring mechanism that closes accurately even under heavy loads, tested to secure up to 2 kg of paper. A Rado stabilising system keeps the binder upright and prevents deformation of the mechanism. Materials are chosen to balance longevity and environmental responsibility: PP foil covering plus recycled cardboard components, and FSC-certified sourcing. The design includes matching colour options and double-sided printable spine labels for easy identification.

Suitable for

• Archiving punched documents, reports and invoices
• Preparing presentations and portfolios for meetings
• Organising project documentation and manuals
• Office filing where a durable, reusable binder is required

Usage recommendations

To maximise service life, avoid overstuffing beyond the 50 mm spine capacity and keep the binder away from prolonged direct sunlight or extreme humidity. Clean the PP surface with a soft, damp cloth; do not use aggressive solvents. For organised filing, use the matching colour range and spine labels to create a consistent system across folders, boxes and journal holders.
