Clear Spiral Binding Coils

Buy clear spiral binding coils online at Binding101 for the best pricing and fastest shipping. This popular colored binder spine is stocked in the full range of sizes 6mm to 50mm so you can bind documents from just a few pages to huge 440 sheet books. We stock a wide variety of pitch patterns, lengths, and sizes to choose from.

 

Coil Binding Pitch

The pitch of a coil binding spine varies depending on your machine; the most common is a 4:1 pitch with 4 holes for every inch of length. 5:1, 3:1, 2.5:1. and 2.231 mm are also available for more specialized applications. "pitch" actually means the holes per inch. So the most popular 4:1 (read aloud as "four to one") has four holes for every one inch of length.

 

Coil Binder Spine Length

The most common length of pre-cut coil binding spirals is 12 inches. This is the best size for a standard letter size 11-inch document. The extra inch of length leaves one half of an inch on each side of your book, which allows you the space needed to cut and crimp the edges of the coil. There are also 36-inch coils available, which led you to choose the length you want for your various or more unique book sheet sizes.
