3:1 Pitch Coil Bindings

3:1 pitch plastic coil bindings feature three holes per inch and are a specialty hole spacing used with specific machinery. Plastic Coil is a great way to add color when binding your book. Measuring at a 12" or 36" length, the pitch for spiral coil bindings can be 4 or 5 holes per inch, with sizes ranging from 6mm (1/4 inch) to 50mm (2 inches).
