## Summary description

Features a 50 mm spine capacity suitable for moderate document volumes, reinforced cover and metal lever mechanism for secure filing, and a label holder on the spine for easy identification.

## Long description

Donau Master A4 50 mm lever arch file in yellow is designed to organise and store A4 documents with a moderate filing capacity. The binder features a 50 mm spine that accommodates punched papers and inserts, a reinforced outer cover for improved durability, a metal lever arch mechanism for reliable sheet retention and a clear label holder on the spine for quick identification. The plain yellow finish makes it easy to sort by colour in offices, classrooms or home workspaces.
Advantages
The reinforced cover provides better protection against bending and wear compared with standard paper folders. The metal lever mechanism allows secure locking and smooth opening and closing for adding or removing documents. The spine label holder enables fast visual identification when stored on shelves. The 50 mm capacity balances compact storage with the ability to hold several dozen punched sheets, while the rigid construction supports upright shelf storage.
Suitable for
Organising A4 documents in offices and administrative environments
School coursework, class handouts and teacher records
Home office filing of invoices, contracts and reference material
Project folders where moderate capacity and colour coding are required
Key specifications
Format: A4
Spine width / capacity: 50 mm
Cover: reinforced, rigid cover for upright storage
Mechanism: metal lever arch for secure document retention
Label: clear label holder on the spine for identification
Colour: yellow
How to use
Open the lever arch mechanism by lifting the lever, align punched paper with the rings and place sheets onto the posts. Close the mechanism until it locks to secure the contents. Use the spine label holder to insert a descriptive label for fast retrieval. Store the binder upright on a shelf or flat in a drawer; avoid overfilling beyond the 50 mm capacity to prevent strain on the mechanism.
Usage recommendations
For reliable performance, distribute heavy content across several binders rather than exceeding the 50 mm capacity. Keep the mechanism free of debris and avoid forcing the lever to extend its service life. Use colour-coded files to speed up retrieval and maintain an organised filing system.
