Gold or Color 6.4-44mm Double Loop Binding Supplies for Diaries
Wire-O binding
Twin Loop Wire-O is available in two standard pitches for different sized books. By using the double loop style to bind documents, it allows the document to fold 360 degrees on its own, which is a solid choice for presentations, calendars, notebooks, and more.
Wire binding is the choice for high-end proposals and is often used by architects, real estate agents, and anyone who wants to have the most professional look. These bindings will work on all wire-bound machines.
2:1 pitch wire is typically used for large books (5/8" to 1-1/2"). 3:1 pitch wire for small to medium books (1/4" to 9/16"). There are also special 2:1 pitch wires for small sizes. There's also the Spiral-O Wire, which has 19 loops and is used as an alternative to comb binding. Wire-O is also known as Double-O Wire Binding, Twin Loop WireBind, Spiral Wirebind, Renz Wire, JBI Wire, GBC Twin Loop Wire-O Book Binding, and Wirebind.
