Spiral-O, Wire-O & Wire Comb. What Is The Difference?

Wire Binding SuppliesTerms like Spiral-O, Wire-O and wire comb are all used to describe what is more commonly known as wire binding. With all these terms floating around, it’s no wonder so many people get confused. I will try and break down exactly why these terms exist and what they mean.

First off, there are three different types of wire binding supplies. These are 3:1, 2:1 and 19-ring pitches. Basically these three formats are different hole patterns. The hole spacing on 3:1 is three holes per inch, 2:1 is two holes per inch and 19-ring is 19 holes along an 11-inch sheet of paper.

Both 3:1 and 2:1 pitch holes can be round or square, although round is far more common. Nineteen-ring holes are always rectangular in shape.  The format you use depends on the look you prefer and the amount of sheets you need to bind.

These are some of the terms used to describe the different wire binding hole formats:

  • Spiral-O – This is another term used for 19-ring wire binding. Nineteen-ring wire hole patters are the same as comb binding.
  • Wire-O – This is a trademarked term commonly used to describe 3:1 pitch wire, although many retailers will use it for 2:1 pitch wire as well.
  • Wire Comb – This is a term used to describe wire (19-ring) that has the same hole pattern as comb binding.
  • Double Loop Binding – A generic term used for all wire binding.
  • Twin Loop binding – Another generic term used for all wire binding.

Wire binding looks great. It holds up well and is available in a variety of colors. You may find our entire selection of wire binding supplies here.
