Ring binder A4 Leitz 42100035 Black

The Leitz 42100035 ring binder for A4 documents is a D-ring binder with a 40 mm spine width, designed to store and organize punched sheets, reports and manuals. Its external dimensions of approximately 275 mm depth and 318 mm height accommodate standard A4 pages comfortably while providing secure document retention and a professional black finish suitable for office or home use.

Advantages

The D-ring mechanism reduces page curvature and allows documents to lie flatter compared with round-ring designs, improving readability and handling. A 40 mm spine provides substantial capacity for up to several hundred sheets depending on paper thickness. The binder's sturdy construction and reinforced spine support frequent handling, while the black cover offers a neutral, professional appearance that blends with existing filing systems.

Suitable for

• Storing and presenting A4 reports, manuals and training materials
• Organizing office paperwork, invoices and contracts
• Archiving project documentation and meeting records

How to use

Open the D-ring mechanism by pressing the designated release levers or tabs, align punched A4 sheets on the rings and close the mechanism until it clicks to secure the pages. For best results, distribute heavy documents evenly and avoid overfilling beyond the 40 mm capacity. Use the spine or front insert (if present) to add labels for quick identification, and handle the binder by the spine when retrieving it from shelves to reduce wear on the cover and rings.

Usage recommendations

Store the binder upright on a shelf in a dry environment to prevent warping and moisture damage. For long-term archiving, separate different document types with dividers and use clear sleeves for frequently referenced pages to reduce wear.
