Key specifications
Format: A4 document size
Ring mechanism: 2 rings for punched sheets
Spine width: 50 mm capacity for multiple pages
Cover colour: white for neutral appearance
Cover type: rigid covers suitable for regular handling
How to use
Open the two-ring mechanism by pressing the designated levers or tabs, align punched sheets along the rings and close the mechanism until it locks securely. Place the binder upright on a shelf or flat on a desk as required. For easy retrieval, insert a spine label or write identification on the cover. When adding or removing pages, open the rings fully to avoid bending the sheets and close them gently to maintain alignment.
Usage recommendations
Use standard A4 punched paper with compatible hole spacing to ensure reliable ring engagement. Avoid overfilling beyond the 50 mm spine capacity to prevent strain on the mechanism. Store binders upright on shelves to minimise cover deformation and handle by the spine for transport. For long-term archives, consider inserting labelled dividers to separate sections and improve accessibility.
