Product Description

Extra-Large A3 Archival Solution with High-Capacity One-Touch Compression for Blueprints and Technical Drawings

The Munhwa File B840-81 A3 Lever Arch Binder is a heavy-duty, professional-grade tool specifically designed for extra-large format documents. Ideal for architectural blueprints, posters, and large financial ledgers, this binder features a premium PP-laminated hardboard for extreme structural rigidity. Its one-touch lever arch mechanism provides powerful compression for up to 600 sheets, while the integrated metal slide rails protect the large bottom surface from friction and wear. It is the ultimate global standard for large-scale document preservation and engineering office management.

- High-Capacity A3 Format Support with a 70mm wide spine, perfectly suited for organizing and protecting large-scale drawings and oversized documents.
- Advanced One-Touch Compression allows you to securely lock down even a full 600-sheet stack with a simple button press, preventing paper sagging.
- Heavy-Duty Metal Slide Rail Protection prevents wear and tear on the bottom edges, ensuring the binder remains durable and professional even on deep shelves.
- Secure Slot-Hole & Finger Ring System featuring rust-resistant plated steel for easy handling and stable, upright storage of large archives.
- Laminated PP Hardboard Construction provides a professional black finish that is moisture-resistant and stands up to the heavy weight of A3 paper.
- 100% Made in Korea quality with a precision concave-convex locking system that ensures perfect ring alignment for snag-free page turning.
