## Long description

Donau Prong Fasteners DONA0684 is a metal prong fastener designed for lever-arch files and ring binders.

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.
