The SAMSILL SAM18987 is a 3-inch round ring view binder designed for letter-size documents in office and school environments. The locking metal rings are mounted on the back cover, which keeps pages lying flat and reduces stress on the ring mechanism during heavy use. The core is constructed from recycled chipboard, and the exterior is covered in acid-free polypropylene, making it a practical choice for organizations with sustainability requirements. Biobased content is tested to ASTM D-6866 standards. This binder is handled primarily by office staff, administrators, and facilities teams managing document storage at scale.
The SAM18987 is suited for standard letter-size (8.5 x 11 inch) document filing in office, educational, and light commercial settings. The 3-inch ring capacity accommodates high-volume document sets. The white polypropylene exterior accepts standard view binder inserts on the front, spine, and back covers, making it easy to customize for project or department labeling. Two clear interior pockets provide additional storage for loose papers, reference sheets, or cover pages without punching.
Designed as a standard replacement or addition for letter-size round ring view binder applications in office and educational filing systems.
No tools are required to load or configure this binder. Before loading documents, confirm ring closure is fully engaged to prevent page loss. Rings are removable for end-of-life disposal; disengage the locking mechanism carefully to avoid deforming the ring assembly. Store flat or upright on a shelf to maintain cover shape under load.
