Document folder Eller 150-03140 A4, 50 mm spine, grey, metal bottom

Eller 150-03140 is an A4 document folder with a 50 mm spine and a grey finish. The folder is designed for upright storage and efficient archiving of A4 papers, contracts and project files. A metal-reinforced bottom increases durability and provides stable standing on shelves or in filing cabinets while the 50 mm spine allows for a substantial volume of documents without excessive bending or compression.

Advantages

The folder’s metal bottom reinforces the base against wear and helps maintain a straight, stable posture when stored upright. The 50 mm spine accommodates a larger stack of A4 sheets than slim folders, supporting neat organization and reduced page deformation. The neutral grey finish offers a professional appearance that integrates easily into office and home filing systems and resists visible soiling. Materials and design prioritize simple handling and long-term use for frequently accessed documents.

Suitable for

• Office archiving of reports, invoices and contracts
• Home paperwork and personal document storage
• Project files and study materials for compact shelving
• Temporary transport of documents between meetings or departments

Key specifications

• Format compatibility: A4 documents
• Spine width: 50 mm for increased capacity
• Closure type: open-top folder with reinforced bottom (metal)
• Colour: grey for neutral appearance
• Storage orientation: designed for upright standing on shelves or in cabinets

How to use

Insert A4 documents vertically into the folder so the spine sits against the shelf edge for stable standing. Arrange papers evenly to avoid uneven pressure on the spine. Use the reinforced metal bottom as the load-bearing surface when placing the folder on high shelves or in mobile trolleys. For frequently used files, label the spine externally so contents are identifiable without removing the folder from the shelf.

Usage recommendations

Store the folder upright on a flat shelf and avoid overfilling beyond the 50 mm spine capacity to prevent deformation. Keep the metal bottom dry and clean to maintain metal integrity and avoid prolonged exposure to direct sunlight to reduce colour fading.
