Wire-O Binding FAQs 

What is Wire-O?

For businesses that need to produce professional-quality books, wire binding is the most popular binding option.  Wire-O spines offer a clean and high-class appeal that no punch-and-binding method can match. Wire-O double-o wires let books lay flat, and the sheets flip a complete 360 degrees. They offer a semi-secure binding method.  

What is Wire Bind Pitch?

The pitch refers to the ratio of holes per inch, so a 2:1 has two holes per inch, and a 3:1 has three. A 2:1 punch machine will only work with a 2:1 binding wire; ensure your wire binding machine has the same hole pattern as the wire spines you purchase.  

What Sizes and Colours are Available?

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. They include the standard black, white, silver, pewter, blue, and red, as well as specialty green, grey, navy and gold (please contact us for specialty colours). 3:1 pitch wire-o comes in sizes from 1/4" up to 9/16" (up to 5/8” in black and white), which means it can be used for books from 2 to 110 sheets (or 220 pages). 2:1 pitch wire-o is available up to 1 ¼", perfect for books up to 230 sheets (or 460 pages).
