Holds up to 540 sheets with slant D-rings that store 25% more paper, plus 30-sheet interior pockets and a clear overlay for customisation
The Business Source 28448 is a 2-inch capacity binder designed for office professionals and students who need to organise large document sets. Its slant D-ring mechanism holds up to 540 sheets, offering 25 percent more capacity than traditional round rings. A clear, non-glare overlay on the front, spine and back allows for customised inserts. The polypropylene cover provides a durable, PVC-free finish.
This binder replaces conventional round-ring models when page volume exceeds their practical limit. The slant D-ring design lets pages lie flat for easier reading and copying, while two triggers give quick access to contents. The jump is worth it for anyone managing thick reports, project files or reference libraries that would otherwise require multiple smaller binders. Inside pockets add 30-sheet storage per pocket for loose items.
The binder fits standard 11 x 8-1/2 inch sheets and uses a sturdy chipboard core with exposed rivets for rigidity. Back-mounted rings keep pages aligned without curvature, freeing up desk space when the binder is open. Clear pockets on the inside front and back covers store unpunched handouts or dividers, reducing the need for separate folders. Sold as a single unit for immediate deployment.

The binder is built for 11 x 8-1/2 inch paper, which is standard US letter size.
Slide the printed sheet into the front, spine and back overlays; the step people miss is tucking the spine insert fully into the narrow spine pocket so it sits flat.
Replace the rings if the two triggers no longer align or if the metal rings stay misaligned after repeated opening, causing pages to catch.
