Ring binder ESSELTE 624071 A4 Blue, 52 mm spine, 318×287 mm

ESSELTE 624071 A4 Blue is a durable ring binder designed for organised storage of A4 documents. With a 52 mm spine and external dimensions of 318×287 mm, this binder accommodates a substantial volume of papers and is suitable for office, school or home filing. The product incorporates a patented closing mechanism with high locking force, ensuring secure and reliable closure over prolonged use. A replaceable spine pocket label, thumbhole, cover lock and metal-reinforced edges improve handling and protect contents during frequent use.

Advantages

The patented No.1 mechanism provides consistently precise closing and a high locking force that remains effective even after extensive use. The binder is constructed to keep pins and arches perfectly aligned when filled, reducing the risk of misfeeds and document damage. A replaceable spine pocket label allows simple identification and personalization, while the thumbhole and cover lock make retrieval and transport straightforward. Metal edges boost durability and protect pages from wear. The binder is rated to hold up to 350 A4 sheets (80 gsm) and includes a three-year warranty on the mechanism.

How to use

Open the binder using the thumbhole and operate the ring mechanism to insert or remove punched A4 papers. Use the cover lock to secure the binder during transport and place a spine pocket label to mark the binder contents. For best results, distribute documents evenly across the rings to maintain alignment and reduce stress on the mechanism. Close the rings until you hear the locking action to ensure documents are held securely.

Usage recommendations

Store the binder upright on shelves to maintain its shape and protect pages. Avoid overfilling beyond the specified 350-sheet capacity to preserve alignment and long-term function of the patented mechanism. Replace the spine pocket label when contents change and keep the metal edges free of dents to ensure smooth closing and handling.
