Product Description
The Heavy-Duty Solution for Massive A3 Archiving: Reinforced 2-Inch Hardboard Binder
The Munhwa B849A-8 is a high-capacity, professional-grade A3 binder designed to organize and protect large-format documents such as blueprints, architectural drawings, and engineering spreadsheets. Built by bonding premium Polypropylene (PP) to an extra-thick hardboard core, it maintains exceptional structural integrity even when loaded to full capacity. This model features industrial-strength metal "Slide Rails" on the base corners to prevent wear from shelf friction, ensuring that your most important large-scale archives remain secure for years to its heavy-duty design.
- Specialized A3 High-Capacity Format: Specifically sized for large-format (A3) documents, providing a massive 2-inch storage capacity for up to 400 sheets.
- Heavy-Duty PP-Hardboard Core: The reinforced construction prevents warping and sagging under the heavy weight of A3-sized paper stacks.
- Protective Metal Slide Rails: Features extended metal rails on the bottom edges to eliminate friction damage when sliding the binder on and off storage shelves.
- Jumbo 2-Inch D-Ring Mechanism: The 75mm spine width and robust D-ring ensure that thick document sets remain perfectly flat and aligned.
- Versatile 4-Sided Pocket Index: A high-transparency spine pocket includes an index card that can be used on four sides, providing ample space for detailed titling.
