Product Description

Books that are bound with wire spools are able to open completely flat and have the capacity to flip pages through a full 360 degrees. This allows the pages to be flipped over all the way till they contact the back of the book. Due to this feature, they are a well-liked option for calendars, particularly when combined with our user-friendly metal calendar hangers.

This Wire-O 7/16" White 3:1 Pitch Double Loop Ring Wire Spool gives a professional metal finish in a variety 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. When combined with the James Burn automatic twin loop wire binding machine, you have at your disposal a flexible binding spine that is not only capable of providing security and longevity, but also does it in an attractive and cost-effective manner.

Have you had a hard time deciding on a diameter for the project you are working on? The sheet capacity chart can provide some guidance, although this will depend on the thickness of the page. It is generally agreed upon that this Wire-O 7/16" White 3:1 Pitch Double Loop Ring Wire Spool is on par with, if not superior to, the Twin Loop Wire Binding Spools manufactured by Renz and GBC.

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

Binding Capacity Chart

Twin loop wire binding can be properly fitted with a few easy procedures.

  1. Lay the book that is being bound flat on a table.
  2. Measure the binding edge's thickness without compressing the paper.
  3. The binding element's size will be determined by adding 1/8" to the measurement.

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.
