Wire-O Twin Loop Binding Supplies

Books that are bound with Wire-O (also known as double o wire or twin loop wire) use a continuous hinge of double loops of wire to hold the book covers and pages together. Wire binding is popular among graphic designers & offers a stylish metal finish. This traditional method of binding secures pages so that they cannot be modified without de-binding the book. Books bound with Wire-O Looped Wire lay flat and the sheets are able to turn 360°, making it the perfect solution for calendars and notebooks. Holes are available in round and square, and 3:1 or 2:1 pitch (holes per inch). The Wire-O supplies are available in 10 different colors and sizes ranging from 1/4" up to 1-1/4", and can even be purchased on spools. The wire can be bent out of shape so this is not the favorable choice for heavy usage and or mailing.

What You Need to Bind with Wire-O:

How to Bind with Wire-O:

    • Position the paper guide on your binding machine based on your desired paper size. Gather your printed sheets and insert the allotted amount of paper into the opening. When the paper is fully inserted, slide the stack to the left until it makes contact with the paper guide. To make sure all of the edges of the sheets are flush, tap the sides of the stack. Activate the punching by using the pull handle, push button, or foot pedal on your binding machine.
    • Arrange your sheets in the desired order. Flip the back cover so that it is on the front of the arrangement. The inside of your back cover should now be the first sheet in your arrangement. You will see in later steps that this will hide the wire spine, making the appearance more professional.
    • Set your Wire Closer to the appropriate Wire-O size that you are using. Set the edge of your book with the wire into the wire closer opening. Pull the wire closer handle to close and secure the wire around you book.
    • Flip the top sheet (your back cover) to the back of the book to hide the spine and see your completed Wire-O Book.
