The Donau Segregator Master FSC A4 ring binder with a 75 mm spine in gray is designed for systematic storage and retrieval of punched A4 sheets and document protectors. Constructed from responsibly sourced materials certified by FSC, this binder provides a durable solution for storing larger volumes of paperwork while maintaining a compact footprint on shelves or in cabinets.

Advantages

This gray Donau ring binder combines a wide 75 mm spine with a robust ring mechanism that supports frequent opening and closing without deforming. The FSC-certified board material ensures that the product is sourced from managed forests, and the neutral color and clean finish make it suitable for professional and domestic environments. Its capacity and firm cover protect documents from creasing and allow neat labelling on the spine.

Key specifications

• Format compatibility: A4 punched sheets and A4 document protectors
• Spine width: 75 mm for large-capacity storage

How to use

Open the metal ring mechanism and insert punched A4 sheets or document protectors onto the rings. Close the mechanism until it clicks to ensure documents are secured and aligned. Place a clear spine label if required for identification, then store the binder vertically on a shelf or in a cabinet. For heavy content, distribute pages evenly and avoid overfilling beyond the 75 mm capacity to maintain ring alignment and cover shape.

Usage recommendations

Store the binder in a dry, stable environment away from direct sunlight to preserve the board and printed labels. Use A4 punched reinforcements for frequently handled pages and consider combining with index dividers for faster navigation through large collections.
