Ring Binder Fasteners Donau blue for lever arch files, pack of 10, model DONA0576

Donau ring binder fasteners in blue (model DONA0576) are metal/plastic attachments designed for reliable document fastening in lever arch files and standard ring binders. Supplied as a pack of 10, these fasteners allow punched papers to be secured and released without damaging the sheets, supporting routine filing, sorting and archiving tasks in office, home and school environments.

Advantages

These binder fasteners combine metal strength with a plastic-coated finish for smoother handling and reduced wear on documents. The blue finish provides visual distinction for colour-coded filing. The mechanism is made for repeated opening and closing while keeping punched documents aligned and firmly held in place. The compact design fits common binder spine dimensions and simplifies retrofitting into existing lever arch files.

Suitable for

• Lever arch files and large ring binders that use standard punched paper
• Office filing, document archiving and record management
• Home paperwork organisation and school project binders
• Replacing worn or damaged binder fasteners in existing folders

Key specifications

• Pack contents: 10 fasteners
• Colour: blue
• Construction: metal mechanism with plastic coating/finish
• Compatibility: designed for use with lever arch files and standard ring binder punched documents
• Function: secure attachment and aligned holding of punched sheets, repeated open/close operation

How to use

To install, align the fastener with the spine mounting holes or the attachment area inside a lever arch file, and secure using the file's existing rivets or screws as appropriate. Insert punched documents onto the rings or prongs, then close the mechanism to lock sheets in place. To add or remove pages, open the fastener, slide the pages on or off the rings, and close the mechanism again. Handle the fastener by its operating lever to avoid bending the prongs and ensure even alignment of documents.

Usage recommendations

Use papers with standard punched holes to maintain secure holding and prevent tearing. For heavy or frequently accessed documents, periodically check the fastener for alignment and wear; replace the fastener from the pack if operation becomes stiff or sheets start to slip.
