TRUBIND Twin Loop Wire Binding Spines - 9/16 inch Diameter - 11 inch Length - 3 to 1 Pitch - Black - 120 Sheet Capacity - 100 per Box

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). These binding wires have loops that are 9/16 inches in diameter. The wires are 11 inches in length and are designed to be used with Letter size documents. However, they can also easily be cut with wire cutters to accommodate books with spines smaller than 11 inches long and can then used with a binding machine equipped with disengaging pins.

Wire-O binding wires from TruBind are fully compatible with all standard wire binding machines, including models from TruBind, Akiles, USI, GBC, Ibico, NSC, Tamerica, Fellowes, and HIC. These heavy-duty, metal binding spines are perfect for reports, presentations, calendars, sketchbooks, as well as other binding projects that require an additional level of sophistication.

With 100 pieces per box, you can access wholesale binding-material pricing while purchasing the right number of wires for your needs. Whether you are binding a few books or hundreds, TruBind provides the quality of materials you need.
