Wire-O® Twin-Loop Binding Supplies (Box of 100)

Item #: WIREOBINDING-CFG

Wire binding is the most popular binding solution for businesses who need to create professional-quality books. The Wire-O® 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. 3:1 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. All sizes 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.

Product Description

Details

Wire-O® binding supplies 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 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. Depending on the capabilities of your wire binding machine, you can choose either pitch or both. 3:1 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.
