Ring binder A4 Leitz 10135015

The Leitz 10135015 ring binder is designed to hold A4 documents securely and to provide durable, easy-to-use storage. Constructed for regular office and home use, this binder uses a D-ring mechanism and offers an internal capacity suited to thick document collections. Its dimensions—81 mm spine width, 285 mm depth, and 318 mm height—make it compatible with standard A4 sheets and most filing systems. The binder is finished in a vibrant yellow color and sold individually.

Advantages

The D-ring mechanism reduces page curling and allows pages to lie flatter compared with round rings, improving document durability and readability. With an 81 mm spine width this binder accommodates large volumes of paper while keeping pages organized and easy to access. The durable cover material provides protection against wear and everyday handling. The bright yellow finish enhances visibility on shelves and helps with color-coded filing systems.

Suitable for

• Archiving and storing A4 reports, manuals and large document sets
• Office filing where high-capacity binders are required
• School or university coursework and project documentation
• Color-coded organization and quick shelf identification

How to use

Open the D-ring mechanism using the release lever or tabs, insert A4 punched sheets evenly across the rings, and close the mechanism until it clicks to ensure sheets are held securely. Store the binder upright on a shelf or label the spine for quick identification. For heavy contents, support the binder at the base when removing from a shelf to avoid stress on the rings and cover.

Usage recommendations

Use appropriately punched A4 paper to prevent damage to documents and the mechanism. Avoid overfilling beyond the spine capacity to maintain ring alignment and reduce wear; periodically check and realign pages if they shift. For long-term archive, store in a dry, moderate-temperature environment away from direct sunlight to preserve the cover color and paper quality.
