Krúžkový blok HERMA 7165 A4 D-krúžkový mechanizmus

The HERMA 7165 A4 D-ring Storage ring binder is designed to store and organize A4 documents with a durable D-ring mechanism. Constructed from sturdy cover material and reinforced edges, the binder provides stable support for multiple sheets while preserving document alignment and protecting pages from wear. Its spine and cover dimensions suit standard A4 folders and make it compatible with shelving and filing systems commonly used in offices, schools and homes.

Advantages

The D-ring mechanism distributes the load evenly and reduces page curling compared with round rings, enabling easier page turning and long-term storage. The binder's rigid covers resist bending and provide protection against spills and light impacts. A clear spine or label area allows easy identification of contents without opening the binder, and the simple, tool-free operation of the ring mechanism supports frequent use.

Suitable for

• Organizing office documents, reports and meeting materials
• Schoolwork, student portfolios and teaching materials
• Home filing of manuals, contracts and personal records
• Archiving frequently used documents that require flat storage

Key specifications

• Format compatibility: A4 document size
• Ring type: D-ring mechanism for even sheet distribution
• Cover: rigid, protective cover material with reinforced edges
• Spine: labelled spine area for easy content identification
• Capacity: suitable for multiple sheets; designed for regular office and school use

How to use

Open the D-ring mechanism using the designated lever or tab to release the rings before inserting punched A4 pages. Align document holes carefully with the rings and close the mechanism until it clicks to secure the pages. Use the spine label area to note the binder contents for quick retrieval. For removal, open the rings and slide pages out, then close the rings to retain their shape.

Recommendations

Store the binder upright on shelves to maintain cover shape and ring alignment. Avoid overfilling beyond the recommended capacity to prevent stress on the D-ring mechanism. Use standard A4 punched paper or sheet protectors when storing frequently handled documents to extend page life.
