Commercial binder features uniquely shaped, Quick Load D-rings to save you time loading letter-size paper. Unique ring shape also results in a double-hinged cover and narrower spine that takes up to 20 percent less shelf space in terms of length and width than traditional, slant-D ring binders yet hold the same amount of paper. The locking rings are mounted on the back cover so pages lie flat. Spine/cover-label wraps around to the front cover for easy label insertion and identification of contents. Material won't transfer ink. Label insert can be printed on letter-size paper and customized with free templates online. Antimicrobial feature inhibits the growth of odor-causing, stain-causing bacteria. Commercial-grade, PVC-free, heavy-duty construction is designed for frequent reference and longevity. Binder also offers two inside clear pockets, exposed rivets, and a high percentage of recycled material.
