The standard length for these traditional plastic binders is 11" with 19 total rings, perfect for standard letter size papers and books. Commonly used for cookbooks and children's books, plastic binding comb spines work perfectly when paired with plastic comb binding machines. They are made of a durable PVC plastic that features a spine with rings attached that open on one side. The spine on plastic combs is one of the unique features that makes comb binders such a popular solution, because they can be custom printed with your company logo, school name, or book title. This economical binding method also allows for easy and fast book editing, as the combs can be re-opened and closed shut as many times as is needed without damaging the book pages.

When choosing your comb size, the best way to ensure the correct diameter of comb for your book is to assemble the entire book (including covers) and let it lay flat and loose on the table (do not press down) and measure the thickness of the stack. Then add 1/8" to that measurement to get the comb diameter recommendation. For example, if your book was 1" thick you would want a 1 ⅛" comb diameter size. If between sizes, we recommend you go with the larger option to ensure that your book pages will turn smoothly and easily.
