2:1 Binding Wire

The double-loop wires are produced open to be inserted in pre-punched holes of the suitable dimensions. Once inserted in the proper holes they are simply crimped closed with a wire closer. The 3 to 1 (3:1) pitch is used for books up to about 12mm thick and 2 to 1 (2:1) wire can be used for books up to about 30mm. 2:1 wire is recognisable as the holes are larger than those produced for 3:1 binding and are spaced further apart. There are 23 holes on an A4 size sheet when it has been punched 2:1, 3:1 has 34 holes on an A4 sheet.

These 2:1 wires are also popular scrapbooking items and are suitable for the popular Bind-It-All machine.

As a general rule of thumb add 3mm to the thickness of your book (uncompressed) to choose the correct wire.
