Product Description

With the assistance of this white 3:1 Wire-O Twin-Loop Binding Spool, you will be able to successfully complete an unique wire book binding. Wire-O binding spools have an alluring metal finish, and they come in a wide range of sizes so that you can bind books anyway you like. These coils of wire are sometimes referred to as twin loop wire binders. This continuous wire binding spine was designed to be compatible with a number of widely used automatic wire binding machines, the likes of which can be discovered in major print and binding businesses. It is rolled onto one massive spool so that it may be easily transported and stored.

Wire binding spools of the highest possible quality are manufactured by James Burn and are available here in our stock. In comparison to wire that has already been cut to a specific length, a spool of wire provides various benefits, the most significant of which is the ability to cut it to any length requested with very little material being wasted. Books that are bound with wire spools have the ability to open entirely flat and feature pages that can be flipped through a full 360 degrees. Because of this, the pages can be turned all the way back until they come into contact with the back of the book. Because of this quality, they are a popular choice for calendars, combined alongside our user-friendly metal calendar hangers.

This Wire-O 1/2" White 3:1 Pitch Double Loop Ring Wire Spool provides a professional metal finish in a range of sizes for books, and it has the capacity to bind up to 11-25 sheets of 20 lb. paper or volumes that are 1/8" thick. In addition, this Wire-O product comes with a lifetime warranty. You have at your disposal a flexible binding spine that is not only able to provide security and longevity, but also does so in a way that is attractive and cost-effective when it is combined with the James Burn automatic twin loop wire binding machine.

Please Note that spool wire is considered a special order item and is non-returnable.

Wire-O binding, the go-to option for professionals of all stripes, provides a tidy, polished appearance that may be found on diaries, notebooks, conferences, guides, and much more. When compared to plastic bindings, the elegant metal finish appears more expensive, so you can be sure to amaze your consumers. They are designed to function with the wide range of automatic and industrial binding machines available today. Twin loop spools provide a very quick and practical way to bind lots of wire-bound books when used with these machines.
