Longer lasting than vinyl binders, heavy-duty polypro binder features never-gap D-Rings to keep papers secure. Locking No-Gap D-Ring mechanism locks rings closed and keeps them aligned so sheets will not tear, fall out or hang up on rings. Metal rings are back-mounted to reduce wear and let pages lie flat. Extra-durable hinge and strong cover ensure these binders are built to last. Material on the cover and pocket resists toner transfer so ink from printed papers won't stick or mark binders. Pocket Guard on both inside covers holds loose papers secure in two interior pockets. Binder also includes a sturdy chipboard core and exposed rivets. Durable construction protects important documents and is made to last.
