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. All 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.
