Cardinal Premier Easy Open Round Ring Binder

Locking round ring on this view binder opens, closes and locks with one simple motion. One-Touch EasyOpen locking mechanism engages instantly when closed, eliminating two-handed, two-step operation. Delayed tension means closing rings will not clamp down and pinch fingers if they get in the way. Once fully closed, the steel spine-mounted rings lock, and the tension engages to secure your papers. 3"" capacity rings hold approximately 575 sheets. Nonglare covers have crystal-clear overlays on the front, back and spine for easy customization. Design also has a sturdy chipboard core, exposed rivets and horizontal pockets on the interior front and back covers. Each pocket holds 40 sheets of loose documents. Binder received the Ease-of-Use Commendation from the Arthritis Foundation.
