Overview
Wire binding is the most popular binding solution for businesses who need to create professional-quality books. These Red 2:1 Wire-O Twin-Loop Binding Spines offer a clean and high-class appeal that is unmatched by any other traditional binding method. Books bound with Wire-O double-o wires lay flat and the sheets can flip a full 360°. They offer a semi-secure binding method that can only be un-bound if cut off.
Available in both 3:1 pitch and 2:1 pitch options for your Wire-O binding machines, these twin loop wire spines come in a large selection of colors including black, white, silver, pewter, blue, green, and several more. 2:1 pitch wire-o comes in sizes from 1/4" up to 9/16", which means it can be used for books from 2 to 120 sheets. 2:1 pitch wire-o is typically available in the larger sizes from 5/8" up to 1 ¼", perfect for books from 135 to 280 sheets, but we also offer unique special smaller 2:1 wires in the full range of sizes, offering more versatility. Select a color, pitch, and wire size below. Wire binding supplies are packaged with 100 wires per box. If you need a custom-cut length, visit our custom wire page for info and to request a quote.

Description
These Red 2:1 Wire-O Twin-Loop Binding Spines are the most popular binding spine in offices and print shops looking for a professional and clean finish. Sometimes called twin loop wire binders, these binding spines offer a stylish metal finish in a variety of colors including black, white, silver, pewter, blue, green, red and more. Wire-O is a semi-secure binding method, meaning that the book cannot be unbound without cutting and discarding the spine itself. Books bound with Wire-O double-o wires lay flat and the sheets can flip a full 360° from front to back, making it an ideal solution for notebooks, journals, and calendars, when paired with our calendar hangers.
Wire binders are available in either a 2:1 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. Depending on the capabilities of your wire binding machine, you can choose either pitch or both. 2:1 pitch wire binding options range in sizes from 1/4" up to 9/16". 2:1 pitch wire binding, however, is available in a wider variety from 1/4" up to the largest 1 ¼" size. Most 2:1 wires only come in sizes 5/8" and larger, however, we offer special smaller 2:1 pitch wires in select colors.
When you bind with wire o spines, you can create a professional, attractive, and clean book up to 280 sheets* thick. Use the capacity chart below to help determine the best size for your needs, and buy wire-o twin loop binding supplies online today.
Wire-O Binding Capacity Chart:
Simple steps to get the proper fit for wire binding.- Take the book being bound and lay it flat on a table
- Don't compress the paper and measure the thickness of the binding edge
- Take the measurement and add 1/8" - that will be the size of the binding element
* Note: the capacities listed below are approximations, determined using standard 20 lb. bond copy paper; the actual sheet capacity will vary depending on the materials being bound.
** Note: The smaller 2:1 pitch wires from 1/4" up to 9/16" are a special-made wire, and are not available in all colors.
