The BUSINESS SOURCE BSN28551BD is a 1.5-inch round-ring binder designed for everyday document organization in office and school environments. It features a two-trigger ring mechanism that allows quick, secure opening and closing of the rings. Back-mounted metal rings keep pages lying flat, reducing bulk and making reading easier. The cover is constructed from durable polypropylene over a sturdy chipboard core, with exposed rivets reinforcing the spine. Each unit ships as part of a bundle of 4, making this an efficient choice for stocking workstations, classrooms, or supply rooms.
This binder is suited for residential offices, schools, and commercial workplaces where consistent document storage is needed. The 1.5-inch ring capacity handles standard 8.5-by-11-inch three-hole-punched paper. Inside front and back covers each include a clear pocket rated for up to 30 sheets, providing additional storage for loose documents, reference sheets, or dividers without punching. The Blue Emerald color aids in color-coded filing systems. Sold as a bundle of 4 units per order.
Designed as a standard three-ring binder compatible with 8.5-by-11-inch three-hole-punched documents, standard tab dividers, and sheet protectors sized for letter-format binders.
No tools are required for setup. Load documents by pressing the trigger levers to open the rings, insert punched pages, then press the rings closed until they click securely. Store binders upright on shelving to prevent warping of the chipboard core over time.
