Divider sheets Donau 1/3 A4 cardboard dividers red, model 8620100-04PL

Donau 1/3 A4 cardboard divider sheets in red are compact separators designed to divide A4 documents into three vertical sections. Made of sturdy cardboard, these divider sheets offer a slim solution for organizing papers in folders, ring binders, filing trays or small document organizers. Their 1/3 A4 format is intended for situations where reduced-width separation is required while keeping documents accessible and clearly segmented.

Advantages

These cardboard dividers combine low weight with structural rigidity to provide reliable separation without adding bulk. The red color creates a visible contrast that helps locate sections quickly. Their compact 1/3 A4 size makes them suitable for tight filing systems and for creating multiple columns within a single A4 sheet capacity. The simple construction ensures easy insertion and removal and compatibility with a range of common office and school organizers.

Suitable for

• Dividing documents into three vertical sections within A4 folders or binders
• Creating color-coded sections in filing trays or desktop organizers
• School projects and classroom handouts that require compact segmentation
• Home administration where space-saving document separation is needed

Key specifications

• Format: 1/3 A4 (vertical third of an A4 sheet)
• Material: cardboard for lightweight rigidity
• Color: red for visual differentiation
• Intended use: separators for folders, binders and filing trays

How to use

Insert the divider sheet into a folder, ring binder or filing tray so that it aligns with the document edges and creates a clear partition. Use the red dividers to separate topics, dates or document types; combine several dividers to form multiple sections. For binders with rings, place the divider where a vertical split is needed and secure other sheets behind it. These sheets can be repositioned or removed as filing needs change.

Usage recommendations

For longer-term filing, avoid exposure to moisture and store in a dry environment to preserve the cardboard’s stiffness. Use the red dividers together with labels or adhesive tabs if you require quick index identification. When used in frequently accessed binders, place heavier documents behind the divider to reduce bending and maintain a neater section edge.
