What is Wire-O?

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 punch-and-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.

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. You will need to be sure your wire binding machine has the same hole pattern as the wire spines you get, because a 2:1 punch machine will only work with a 2:1 binding wire.

How many loops do 3:1 and 2:1 pitch wires have?

2:1 wires feature 21 loops and 3:1 wires feature 32 loops.

How long are binding wires?

Binding wires are either pre-cut to 11" lengths for standard letter size paper, or continuous and wrapped around a spool.
