36" 4:1 Spiral Binding Color Coil

The standard hole/punch pattern is spiral binding with a 4:1 pitch (4 holes per 1′′), sometimes known as 6mm. 4:1 pitch spiral coils specify that there are four holes per inch at the document's binding edge. For this style, the holes or punch patterns are typically either round or oval. The diameters of the components for 4:1 pitch spiral coil document binding range from 6mm to 50mm, supporting documents with a maximum thickness of two inches. It is perfect for conferences, calendars, instruction manuals, and recipes. When open, it may rest entirely flat and turn from cover to cover. Sometimes referred to as plastic coil binding, you have over 36 color options to choose from. Its many color possibilities make it very simple to match and coordinate with your report cover stock.
