Wire-O binding spools, also known as twin loop wire binders, come in a variety of sizes and have a nice metal finish. This wire binding spine, which is rolled onto a big spool, is designed to function with several common automatic wire binding equipment found in major publishing and binding shops. James Burn produces the best-quality wire binding spools, which are proudly carried from MyBinding. You can cut a spool of wire to any length you need, with less waste, compared to pre-cut wire.

Spools for wire binding are available in a wide range of colors and sizes. First, select a color from a range of formal shades, such as black, white, silver, pewter, blue, green, and more. Next, decide which wire diameter you require. Check out the capacity chart below for some suggestions based on the thickness of your books if you need assistance choosing the right diameter for your project. The pitch will be predetermined based on the size you choose. While bigger sizes from 5/8 inch to 1-1/4" have a 3:1 pitch, sizes from 1/4 inch up to 9/16 inch do not. Want us to cut the wire to your specifications? No issue! For additional information about custom wire binding spines, visit our custom wire page.

A Wire-O Twin-Loop Binding Spool can be the ideal option for bulk wire binding in your large print or binding shop.

Wire-spool bound books can be fully 360° flipped, allowing you to turn the pages over until they touch the back and lay flat when opened. They are, therefore, a well-liked option for calendars, particularly when used with our simple metal calendar hangers.

The loop count used to determine the size of a Wire-O spool varies based on the wire diameter chosen. For instance, the tiniest 1/4" wires have 90,000 loops, while the biggest 1-1/4" wires have 2,900 loops on one spool. The chart below shows the various loop counts per spool. It can be used to choose the optimal wire size depending on your unique requirements, either using an approximate page capacity or an approximate book thickness.
