TruBind 9mm (11/32 in.) 4:1 Pitch 12 in. Binding Coils (100/bx)

Spiral coil binding offers both a professional, finished look to documents and a "lay-flat" design with the ability to flip pages 360° from front to back. Plastic coils such as TruBind's 4:1 Pitch 12 in. Binding Coils are an excellent high-quality choice for business proposals, annual reports, company presentations, restaurant menus and more!

All Standard TruBind binding coils have a 4:1 pitch (4 holes per inch) and are fully compatible with any matching 4:1 pitch coil binding machine; models include brands such as Akiles, USI, GBC, Ibico, NSC, Tamerica, Fellowes, Rhin-O-Tuff, Renz, and HIC.

These plastic coils are available in a 12 in. length and are designed to be used with Letter size documents, leaving excess on either edge to allow for crimping the ends shut with pliers. (We do have select diameters available in 36 in. lengths here on our website for books with spines more than 11 in. long.) These plastic coils can easily be cut to accommodate books with spines smaller than 11 in. long and can then used with a binding machine equipped with disengaging pins.
