Every in-office binding project needs the perfect binding supplies to make it complete. TruBind 13-mm (1/2-inch) Binding Coils allow you to create professional-looking bound projects affordably and easily. Spiral coil binding offers documents both a professional, finished look and a lay-flat design with the ability to flip pages 360 degrees from front to back. These plastic coils are an excellent high-quality choice for business proposals, directories, staff handbooks, annual reports, company presentations, restaurant menus, and more! Plastic spiral coils from TruBind are made of high-quality plastic that wonâ€t bend or snag. Each coil is pre-cut to 12 inches long, making them the perfect choice for binding spines for standard letter-sized documents. Plenty of excess is included so that you can crimp the ends for a finished look or simply trim them down if you need a slightly smaller size. TruBind plastic coils can be used with any binding machine with disengaging pins like all our TruBind machines. Each TruBind Binding Coil is 13mm, or 1/2 inch in diameter, with 48 loops per 12-inch coil. This provides the right durability and holding strength for most in-office binding projects. All standard TruBind binding coils have a 4:1 pitch, which means they will fit any binding machine that punches 4 holes per inch. TruBind Plastic Binding Coils provide the flexibility you need to create affordable in-office projects. Our plastic coils can hold up to 105 sheets of standard 20lb copy paper when bound. That equals a maximum binding capacity of 11/32 inches of thickness, perfect for most office projects. With 100 pieces per box, you can access wholesale binding-material pricing while purchasing the right number of coils for your office needs. Whether you are binding a few books or hundreds, TruBind provides the quality of materials you need.
