Overview

These 6mm spiral coils (1/4") will bind up to about 35 sheets of 20 pound bond paper, or about a 5/32" thick stack of pages. They are blue coils that offer a bright, vibrant finish that goes well with many branding choices. They have a special 5:1 pitch hole spacing for compatibility with any specialized 5:1 pitch coil binding punch machine (keep in mind; these are not 4:1 pitch coils). These coil binders are 12" long for standard letter size pages measuring 11" on the binding edge; the extra 1/2" on each end is essential to allow for cutting/crimping-in of the ends. The plastic material makes them flexible, durable, and perfect for personal, education, or professional document bindings of all kinds. These spiraled binder spines are packaged with 100 coil spines per box.

Description

Spiral binding plastic coils are one of the most popular traditional binding methods available. They consist of a continuous spiraled coil that is made of durable and flexible plastic and is rolled into holes along a binding edge. Spiral binding coils offer a more modern and durable way to bind books over the traditional comb spines, while still being affordable and simple to use. Another benefit of spiral binding coils over many other binding methods it that, coil bound books have the ability to flip pages completely around a full 360 degrees without damaging the contents, so they can lay flat and stay flat. This allows your book pages to flip all the way around from front to back for easy readability. They bounce-back to their original shape, even after heavy use and bending. Plus, the plastic material can easily be sanitized between users (just pair with contents that are laminated / fully encapsulated for an easy-to-clean solution).

What Kind of Coils Do I Need to Buy?

We offer a huge selection of spiral binding coils for you to choose from, most stocked in all our nation-wide USA warehouses for fast shipment and delivery. There are four different categories of coil to choose from, including the length of the coil, the pitch, the diameter (or coil size), and the color. Here are the steps to follow for how to choose the binding coils you need to buy.

1) Choose a Coil Length

First, choose your coil length. 12" coils are made for letter size pages and are the most popular choice. 36" length are a bit more specialty, primarily used by print shops are those wanting to make multiple books from one single coil spine. 36 inch length coils are also great for oversize and jumbo books.

Need a different length? You can easily cut down the above stocked coil lengths to the size you need, but sometimes that is not the most efficient option for larger quantities. If you need 100 or more coils of a specific length, consider custom cut coils instead. And remember to order 1" longer than your document length so you have that extra 1/2" on each end that allows for cutting/crimping in and finishing the bind.

2) Choose a Coil Pitch

Once you have chosen the length of your coil bind spine, choose your pitch. What is a binding pitch? Pitch refers to the holes per inch, or the hole spacing. They are reflected in a ratio that includes the number of holes, a colon punctuation, and then the inch measurement...for example, 4:1 is pronounced “four to one” and means that there are 4 holes for every 1 inch and 5:1 means there are 5 holes for every 1 inch.

4:1 pitch binding coil spines are by far the most popular, as it is the standard spacing for coils in the United States. About 98% of our customers order 4:1 pitch spiral bindings. The 5:1 is a specialty spacing that is manufactured primarily for print shops that have specialty equipment for punching the pattern, and users who may have machines manufactured in other countries where the 5:1 spacing is more common. You will want to check your spiral binding machine for compatibility before you buy spiral binders online.

3) Choose a Coil Size / Diameter

Now choose your coil size (diameter) for your document. You can use the coil bind capacity chart below to help choose the best size based on your stack thickness or your sheet capacity. Just note that the sheet capacity was calculated using sheets (not pages) that were all 20 lb. bond copy paper, without any covers; this means it can vary significantly depending on the stock you are using, which is why we recommend the stack thickness method instead. And remember: having a coil that is slightly too large is better than having a coil that is too small; a small coil won't allow pages to flip smoothly and can pinch them, tear more easily. So if you are between sizes, we recommend you size-up.

There is also a general rule with three simple steps to get the proper fit for spiral binding that works as well:

1. Take the pages and covers being bound and lay the stack flat on a table.

2. Measure the thickness of the stack, but don’t press down; let it lay naturally loose.

3. Add 1/8" to the stack thickness - that will be the size of the binding coil recommended for your document thickness.

4) Choose a Coil Color

Lastly, choose your coil binding comb color. Stocked colors for most sizes and pitches include black, white, clear, royal blue, navy blue, red, and silver. The colors are solid, not coated, so even with heavy use and scratching, they will remain. Black coils are the most popular choice, while white and clear are close behind. Maroon and navy blue are popular choices for professional institutions, as they often match corporate branding. Red and royal blue are brighter and more vibrant than the others, so are more common for schools and other organizations where brighter colored coil bindings are needed.

* The sheet capacity rating above was calculated using all 20 lb. bond paper, with no covers and no other paper stocks. The actual sheet capacity will vary depending on what paper stock and covers you are using. For this reason, we recommend you use the stack capacity for a more accurate fit. All of these capacities are approximations. If you are between sizes, we recommend you size-up to allow for easier page-turning.
