2:1 PITCH WIRES

This punching has 2 holes per inch (25mm).

While it is mainly used for larger books of between 12.7mm and 38mm,

we also stock smaller sizes from 6.4mm to 11mm of binding wires in this pitch.

If using the smaller size wires it is necessary to adjust the depth gauge to ensure pages can open.
