Heavy-duty binder features One Touch EZD locking rings that open with ease and keep pages secure. Gap-Free ring design prevents gapping and misalignment of rings. Pages lie flat with these back-mounted rings. EZD rings hold up to 50 percent more than same-size round rings. 2" ring capacity accommodates approximately 540 sheets. Wide front and back binder panels fully cover standard dividers and sheet protectors so you can keep your letter-size paperwork and tabs protected. Binder also offers exposed rivets on back and a sturdy chipboard core. Four durable, clear interior pockets store handouts and loose or unpunched pages. Each pocket holds up to 40 sheets. Cover material is PVC-free polypropylene.
