4:1 Plastic Coil - 36" Length
Spiral binding plastic coils are one of the most popular traditional binding methods available. They are made of a continuous coil that is made of a durable and flexible plastic that is spun through several closely spaced holes, and then crimped in on the edges. They allow your book pages to flip all the way around from front to back, and are extremely flexible and durable, so will bounce-back to their original shape, even after heavy use. This makes them ideal for schools, travelling sales people, product manuals, and so much more. If you're ready for one of the most durable binding spines available, then buy standard spiral binding plastic coils online at CFS Binding Supplies.
Spiral binding coils offer a more modern and durable way to bind books over the traditional comb spines. Plastic spiral binder spines are made of continuous plastic coil, similar to a phone cord. To bind, these plastic coils are spun through a series of closely spaced round holes, (the most common spacing being 4 holes per inch, called a 4:1 pitch) and the edges are then crimped in. A benefit of spiral binding coils over many other binding methods it that, once bound, books that the ability to flip pages completely around a full 360° without damaging the contents, so so they can lay flat and stay flat. Great for office presentations, school story books and more. Our spiral coil bindings are durable and keep their shape, even after bending or with excessive use, making them great for schools and other industries where books will be frequently handled. The variety of colors available is vast, with colors including black, white, clear, red, blue, maroon, green and more! We even offer special-order colors, custom colored coil, and custom cut sizes. Sizes range from 6mm (1/4") up to 50mm (2") allowing for books as thick as about 440 sheets of 20 lb. bond to be bound.
