Plastic Coil Binding (Standard)
Plastic Coil Binding (Standard) 5:1 Pitch
COMES IN QUANTITY OF 100 PCS
The common hole / punch pattern is 4:1 pitch (4 holes per 1″) spiral binding; or sometimes referred to as 6mm. 4:1 means there are four holes per inch on the binding edge of the document. The holes / punch pattern for this style are usually either round or oval shaped. Elements for binding documents with 4:1 pitch spiral coil are available in sizes ranging from 6mm up to 50mm in diameter. Allowing binding documents that are up to two inches.
3:1 pitch (3 holes per 1″) spiral binding / coil is less common. Designed for use with the hole pattern used in Wire Binding (twin loop, double loop) or with GBC Proclick. 3:1 pitch spiral coil is easier to use for large diameter books because there are less holes / punch patterns to run the spiral / coil through. Spiral binding elements for this hole pattern are available in sizes ranging from 6mm up to 50mm.
Not as common as 4:1 pitch spiral / coil, some prefer to use 5:1 pitch (5 holes per 1″) spiral binding / coil or referred to 5mm they interchange. With five holes per inch, 5:1 pitch spiral / coil is tightly bound and provides a cleaner appearance. The limiting factor with 5:1 or 5mm pitch is that it only binds up to 25mm- not a good choice for larger documents as they are more difficult to bind function as a document.
