Product Description
This 12" Black 25mm 5:1 Pitch Spiral Binding Coil is designed for use with your 5:1 pitch coil punch for a special, tightly-wound coil binding. These 5:1 spirals provide a similar look and feel that you get with the more common 4:1 pitch coils. The primary difference is 5:1 pitch coil is designed for a hole pattern with five holes per inch (5:1). The tighter hole pattern offers a more elegant bind for your documents. Sold in quantities of 100, 5:1 pitch coils are available in sizes from 6mm up to 25mm in diameter (about 1/4" to about 1"). See below for a list of sizes and approximate capacities.
