Hanging folder Donau with metal tongue, A4, 230 gsm, brown

Donau hanging folder with metal tongue for A4 documents, manufactured from 230 gsm board in brown, provides a durable solution for filing and protecting papers. The folder includes suspension rails that allow it to hang in standard filing cabinets and drawers, and a metal tongue closure secures documents during storage and transport. Designed for office and archival environments, it helps keep invoices, contracts, project files and other A4 materials organized and accessible.

Advantages

The 230 gsm board offers increased rigidity compared with standard paper folders, reducing bending and damage to contents. The metal tongue closure ensures that loose sheets remain inside when folders are moved or stacked. Suspension rails are compatible with most A4 filing systems, enabling smooth sliding and stable positioning in cabinets or drawers. The neutral brown color provides a professional appearance and makes it easier to group and label files visually.

Suitable for

• Office filing of invoices, contracts and correspondence
• Archival storage of project documentation and records
• Transporting documents between sites or departments
• Organising client or case files in cabinets and drawers

Key specifications

• Format: fits A4 documents
• Material: 230 gsm rigid board
• Color: brown
• Closure: metal tongue for secure fastening
• Mounting: built-in suspension rails for hanging in cabinets and drawers

How to use

Insert A4 documents into the folder so that they rest flat against the board. Engage the metal tongue to hold loose sheets securely; ensure the tongue is fully inserted to prevent pages from slipping out. Place the folder by hooking the suspension rails onto the rails inside a filing cabinet or drawer, allowing the folder to slide smoothly for retrieval and re-shelving. For transport, keep the metal tongue fastened and stack folders upright to minimize shifting.

Usage recommendations

For best results, label the folder spine or front edge before filing to speed up identification. Avoid overfilling beyond the folder’s capacity to maintain closure effectiveness and prevent stress on suspension rails. Store in a dry environment to preserve board integrity and prolong service life.
