ProductDescription

MyBinding is excited to introduce this one of a kind, heavy duty spiral coil exclusively designed for use with a 3.2 to 1 pitch hole pattern (or 0.313 hole spacing). It can be used with a true, but not as common 3.2:1 pitch hole pattern (mostly available for large industrial binding punches) or the more common 3:1 wire binding hole pattern for binding large sized books with coil. The 3.2:1 diameter pitch is comparable and similar to 3:1 or 2.5:1. This special and limited type of coil length is only available in sizes greater than 23mm and it utilizes a more rigid filament to make the inserting process easier. 3.2:1 pitch coil is available in sizes from 23mm up to 50mm in diameter and with more than 45 colors, there's undoubtedly a color that will satisfy your eyes. In the past, binding large documents with coil was a huge pain but by using this coil, the process should be a whole lot easier.
Please Note that our 3.2:1 pitch coil is made to order, is non-returnable and can take an extra 1-2 business days to ship. If you need this product in a hurry please give us a call for options before ordering.
