Locking D-Ring View Binder features no-pinch rings that open, close and lock with one touch. D-ring design holds more sheets than standard round-ring binders. Locking steel rings are mounted to the back instead of the spine so pages lie flat. 1-1/2" ring capacity holds approximately 325 sheets. Clear, nonglare overlay holds custom title sheets. Acid-free polypropylene construction prevents contents from sticking to the binder cover. Four horizontal pockets are stacked inside front and back covers to maximize storage space on the covers. Each pocket holds 30 sheets. Binder also features exposed rivets and a sturdy chipboard core.Locking D-Ring View Binder features no-pinch rings that open, close and lock with one touch.
