Wire Binding Supplies come in many different colors, sizes and in two wire pitches:
3:1 - which has 32 loops in an 11" sheet of paper
The
3:1 pitch starts at 3/16" and goes to a maximum binding thickness of 5/8", or about 125 sheets.
The
2:1 pitch has 21 holes on an 11" sheet of paper, starts to bind at 1/4" and continues through to bind up to 1 1/4".
The wire supplies come packaged in boxes with paper and cardboard to hold and separate the wire binding spines.
Wire Binding is also called Twin Loop Binding, Double O,loop wire or Wire-O. Differences are just manufacturers names for the wire binding machines and wire supplies.
When you bind a book or document with wire, be sure to put the two cover sheets together before the crimping and binding process. This will hide the binding spine in between the last sheet of the booklet and the back cover sheet, showing off your document, and not the crimped binding spine.
