Transcript: This is the Carl’s Steel Spiral Wire Coil!

This is the Carl’s Steel Spiral Wire Coil! You can find it it two sizes: the 9 mm size can fit up to 50 pages, and the 18mm size can fit up to 110 pages. When bound, pages lay flat. Better yet they lay back to back! After punching with either the Carl Ring Binding System, or any other 3:1 pitch punch machine, thread the coil through the first holes by hand. Finish it completely this way, or finish it with a coil machine. Afterwards, cut off the extra coil on the ends. You can use coil cutting crimpers as seen here, or cut and bend the ends yourself with pliers. This stops the ends from going through the holes. Here is a look at the difference between 4:1 plastic coil, and this 3:1 steel coil. Carl sells 4 different colors of wire coil, but not all colors have a 9mm sized option.

Thank you for your question. Comb binding is not going to be a 2:1 pitch. What that ratio is is the number of holes per inch. 2:1 would have 2 hole per inch. The type of wire you would use that has the same spacing as comb is called Spiral-O. You would need to have a wire closer to use Spiral-O wire. You can find our selection of Spiral-O wire here .
