GBC Document Wire Binding Elements

  Wire-O binding wire, also called "duo-wire" or "twin-loop binding wire," is a versatile binding spine that offers security and durability, but with style and affordability. These wire spines are perfect for reports, presentations, calendars, sketchbooks, as well as other binding projects that require an additional level of sophistication. These 1/4", 3:1 pitch wire-O binding wires are designed to fit the distinct hole pattern of a 3:1 pitch wire binding machine (three holes per inch, giving 32 holes per Letter size sheet). These heavy-duty, metal binding spines are fully compatible with all standard wire binding machines. Sturdy spines won't scratch, chip, peel or discolor over time. Reliable spines are excellent for busy offices.
