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. 3:1 pitch wire-o binding wires are designed to fit the signature hole pattern of a 3:1 pitch wire binding machine (three holes per inch = 32 holes per letter-sized sheet). Wire-O binding wires from Lamination Depot are fully compatible with all standard wire binding machines, including models from Akiles, USI, GBC, Ibico, NSC, Tamerica, Fellowes, and HIC. These heavy-duty, metal binding spines, available in a wide range of colors and sizes, are perfect for reports, presentations and other assorted book binding projects.
Our binding wire spools are suitable for documents larger than standard letter size or for use in industrial environments.
