Desk tray organizer Donau Biella 7470001-04, Polystone, Red, C4, 370×256×70 mm

Donau Biella 7470001-04 is a red desk tray organizer made from durable Polystone in C4 format with interior dimensions of 370 × 256 × 70 mm. Designed to receive C4 envelopes and similarly sized documents, this tray provides a stable, rigid surface for sorting and storing paperwork, folders and small office supplies. Supplied in packs of 10, the tray is suitable for busy office environments, reception areas and shared workspaces where clear document separation and quick access are required.

Advantages

The Polystone construction offers impact resistance and dimensional stability compared with thin plastic trays, reducing deformation under regular use. The C4 format and specified interior dimensions ensure compatibility with standard C4 envelopes and most A4 folded formats, enabling efficient stacking and filing. The red color provides clear visual identification within multi-tray systems, aiding organization and workflow.

Suitable for

• Sorting incoming and outgoing mail and C4 envelopes
• Organizing project folders and stacked documents on desks or shelves
• Reception desks and mailrooms where quick visual identification is needed
• Temporary storage of office supplies such as notepads, forms and small folders

• Format: C4 compatible

How to use

Place the tray on a desk, shelf or reception counter with the open side facing the user for easy insertion and retrieval of documents. Use one tray per category (for example: incoming, outgoing, urgent) or stack several trays to create a vertical filing arrangement. Slide C4 envelopes, folded A4 papers or thin folders into the tray so they lie flat against the base; avoid overfilling beyond the 70 mm interior height to maintain stack stability. Clean the tray with a soft cloth and mild detergent if necessary.

Usage recommendations

For durable organization, combine several trays in alternating colors or labels to create a color-coded filing system. Avoid exposure to direct sunlight for prolonged periods to prevent color fading and store trays flat when not in use to preserve shape.
