Product information

Description

Donau Prong Fasteners DONA0684 is a metal prong fastener designed for lever-arch files and ring binders. Supplied in navy, this mechanism secures punched documents on two prongs and is intended for reliable, long-term mechanical binding of loose sheets in office and archival environments. The metal construction ensures stable alignment of papers and straightforward operation when adding or removing pages.

Advantages

The metal construction provides durability and resistance to deformation under normal office use. The two-prong design offers a secure grip on punched documents while keeping sheets aligned. The navy finish gives a subdued, professional appearance suitable for corporate and archival settings. Installation and operation are simple, allowing stable fastening without complex tools.

Suitable for

  • Lever-arch files and large-capacity ring binders
  • Office document organization and filing
  • Archival storage of punched sheets
  • Manual binding where a durable metal fastener is required

Key specifications

  • Material: metal
  • Colour: navy
  • Mounting style: two prongs for punched paper
  • Application: lever-arch files and binders
  • Typical use environment: office and archive

How to use

Align the fastener with the pre-punched holes of the documents and the mounting positions within the lever-arch file. Insert the prongs through the punched sheets, then fold the prongs over or secure them according to the binder's mechanism so that papers are held flat and aligned. To remove or add pages, unfold the prongs, adjust the paper stack, and refold to secure. Ensure the fastener is mounted firmly to the binder spine or base so that it remains stable during handling.

Usage recommendations

Use with correctly punched documents to avoid tearing and ensure long-term preservation. For archival storage, keep binder and fastener in a dry, temperature-stable environment to prevent corrosion and paper degradation. Periodically check the fastener for wear or bending and replace if alignment or retention is compromised.
