Locking rings of the EasyOpen Clearvue Slant-D Ring Binder open and close with one touch. 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. Binder received the Ease-of-Use Commendation from the Arthritis Foundation. EasyOpen Slant-D rings hold 25 percent more sheets than standard round-ring binders. Back-mounted steel rings reduce wear and let pages lie flat. 4" ring capacity accommodates approximately 775 sheets. Horizontal inside pockets offer storage for loose documents, and each pocket holds 40 sheets. Clear, nonglare overlays on front, back and spine hold custom title sheets. Design also includes exposed rivets and a sturdy chipboard core.
