TruBind 22mm 7/8-Inch Black Coil Bindings, Set of 50 (COIL22-BK);

Coil Binding is one of the most popular binding methods due to its professional appearance and its "lay-flat" design, or ability to flip 360 degrees. Perfect for business proposals, annual reports, company presentations, and any other book binding project, spiral binding coils from TruBind are made of high quality plastics and are a practical alternative to costly name brand binding coils such as GBC ColorCoil binding spines! All TruBind binding coils have a 4:1 pitch (4-holes per inch, 48 loops per 12" coil) and are fully compatible with any 4:1 pitch coil binding machine - including models from Akiles, USI, GBC, Ibico, NSC, Tamerica, Fellowes, Rhin-O-Tuff, Renz, and HIC.
