Satisfy your need for a large-capacity binder with multiple content options. Binder expands so even if you're organizing a catalog, everything will fit. Telescoping posts make adjusting the width of this binder a breeze; just pull the cover and you're done. Binder also has a slide-action binding mechanism to keep contents tidy. Make content changes efficiently with the transfer bar system that allows you to add, remove or substitute paper into the front, back or in-between existing pages. Metal hinges reduce wear-and-tear on the binder.
