Wire-O Twin-Loop Binding Spines are the most popular binding spine for making journals that are looking for a professional and clean finish. Sometimes called twin-loop wire binders, these binding spines offer a stylish metal finish. Bound documents open easily, lie flat, and completely fold over 360°
Wire binders are available in either a 3:1 pitch (pronounced "three to one" and with 3 holes per inch) or a 2:1 pitch (pronounced "two to one" and with 2 holes per inch) options.
Use the capacity chart below to help determine the best size of wire and pitch requirement for your journal. This charge is prepared based on 60# uncoated paper!
