Heavy-duty view binder is easy to use with One Touch EZD locking rings. Special ring design increases capacity, makes rings easy to open and keeps pages secure. Gap Free ring feature prevents gapping and misalignment of rings. Your letter-size pages lie flat with back-mounted metal rings. EZD rings have a higher page capacity compared to same-size slant and round rings. 4" ring capacity accommodates approximately 780 sheets. Organize and secure loose paper with four clear interior pockets. Each pocket holds up to 20 sheets. Wider front and back binder panels fully cover standard dividers and sheet protectors so you can keep your paperwork and tabs protected. Customize the binder with the crystal-clear poly overlays on the front, spine and back. Binder is made out of heavy-duty poly. Nonstick material won't lift ink or toner off printed pages. Binder also features exposed rivets and a sturdy chipboard core.
