4:1 Pitch 12" Plastic Coil (100 pcs/bx) / *4:1 Pitch 12" Plastic Coil 45 - 50 mm (50 pcs/bx)

Create an impressive presentation with these colorful binding spines. Color coil adds energy to your reports and proposals, and demands attention. This spine always keeps its shape with bounce-back flexibility. It lets pages lie flat with 360 degree rotation for convenient note taking and photocopying. Its bind is permanent, so you can be sure documents stay organized. To determine the coil size for your document, measure the thickness of the document sitting on a flat surface and add 2 mm. These plastic coils are compatible with spiral coil binding machines.

4:1 pitch (meaning 4 holes per inch of your document) is the most standard, typical binding size you will come across. 5:1 pitch is also available and provides a cleaner finish due to tighter coils, but the offside is that larger diameters are not possible and there is a more limited range of book thicknesses it is possible to bind. Finally, there is a specialized 3:1 pitch available, meant as a plastic alternative to Twin/Double Loop Wire or GBC Proclick and is easier for binding larger books due to less coils per inch to thread the coils through.

These coils are also available in a longer 36" length perfect for cutting down to your desired length. However, the 36" coils are too long and do not come in the full range of diameters, only reaching 35 mm max.
