Slant-D reference binder features no-pinch rings that open and close for easy access to your tabloid-size documents. Lock with just one touch. Binder holds 25 percent more than standard round-ring binders. Back-mounted steel rings reduce wear and let pages lie flat. Binder also offers a label holder for easy reference and exposed rivets. Durable, heavy-gauge vinyl cover and a sturdy chipboard core protect your contents. Binder is made with a high percentage of recycled material.
