Business Source BSN09978 Round Ring Binder 3 Inch Black

Product Description

The BUSINESS SOURCE BSN09978 is a 3-inch capacity round-ring binder built for organizing and protecting documents in office and school environments. The back-mounted metal ring mechanism keeps pages lying flat, reducing dog-eared edges and misalignment during page turns. Two trigger releases on the ring mechanism allow quick, one-handed access to documents. The cover is constructed from durable polypropylene over a sturdy chipboard core with exposed rivets, giving the binder rigidity without excess bulk. Clear interior pockets on both the front and back covers each hold up to 30 sheets, adding convenient storage for loose reference materials, cover sheets, or inserts.

This binder is suited for general document management in offices, classrooms, and administrative settings. The 3-inch ring capacity accommodates a substantial volume of standard 8.5-inch by 11-inch three-hole-punched paper. The flat-page design makes it practical for presentations or reference binders where consistent page alignment matters. Office administrators, educators, and records management staff are the typical end users. No special tools are required for loading or unloading pages.
