Wire-O Bound Books

Wire-O Binding, also known as Twin Loop, Double-Loop, Double-O, Duo-Wire, or simply Wire Binding, is an attractive method for joining the pages and cover of a bound document.

Wire-O binding offers many of the same benefits as spiral coil binding, but is more sophisticated in appearance. As such, it produces a very impressive document. Also, it can accommodate pages and inserts of varying thicknesses, including dividers or index tabs made from heavy cardstock.


The Wire-O binding method utilizes pre-formed pairs of wire loops that run along a C-shaped unit. These wire loops are inserted through holes that have been punched through the book’s cover and pages. The loops are then crimped closer together until they form a perfect circle, thus securing the cover and pages as an assembly, yet allowing them to open freely.





Widely use for stationery items. such as reports,books,surveys,sales presentations, reference materials, training manuals, cookbooks,calendars, notebooks,proposals,summaries etc.


Benefits of Wire-O Binding

  • Books open 360 degrees (cover to cover) which allows them to fold flat and lie flat for easier reference.
  • The dual wire coils add a very distinctive appearance to bound documents.
  • It is a readily available binding method.
  • Can be used for very short production runs...for example, 200 books.
  • This method is excellent for wall calendars and planners because it allows them to hang completely flat against the wall.
  • This binding style works well with index tabs.
