Product Meets or Exceeds expectations Review by Digital Print Center

We recently reviewed the pricing on many of the products we use in our shop and found MyBinding to save us a few dollars.
I was pleased that the product was just as good, maybe a tad better, than the product we had been using.
Thank you.

Welcome to MyBinding video. This is everything you need to know about spiral coil. First, there are sizes ranging from a 6mm diameter all the way to 50mm. The smallest size can hold up to 30 pages and the largest can hold up to 444. A great benefit to spiral coil is that the pages lay flat. Better yet, they fold nicely back to back and the choices of color is one of the largest in any type of binding. Standard size coil has a 4:1 pitch, which is compliant with its respected hole punches. The standard length of each coil is 12 inches. Coil should always be longer than the pages you're binding. There are also custom lengths up to 36 inches. With the extra length on each end, you finish off your book with special wire cutting crimpers. Once you're done, you'll have yourself a spiral coil bound book. For more demos, reviews and how-to's, go to MyBinding.com.

Questions & Answers

Do you need wire cutter pliers for plastic coils? Will the pliers bend the plastic like they will bend wire at the end so the pages don't fall out? or are the pliers just for metal wire?

Asked by Sara

Thank you for your question. To crimp and trim the standard plastic binding coils you would want to use a pair of Crimping Pliers. You can find our section of Crimping Pliers here .

Answered by MyBinding 8 months ago

If I punch my holes with the cinch, can I wind a sprial coil through with no issues?

Asked by Meredith

Thank you for your question. It would depend on what pitch the Cinch punches. These are a 4:1 coil ( 4 holes per inch). If the cinch punches a 3:1 pitch hole pattern you are able to order custom cut coils here . If the Cinch punches a 2:1 hole pattern unfortunately there is not a plastic coil available that matches a 2:1 pitch.

I want to use these coils for a menu, will these stand up to the daily abuse a menu endures?

Asked by Jorge

Thank you for this excellent question. The spiral coils will work with a menu. However, to endure the daily abuse we do offer a thicker filament for the coils. .70, .83 and .93. These are not listed on our website, so please call In and let us know what you are looking for and we will be happy to assist you. 1-800-944-4573

Answered by MyBinding.com 2 years and 10 months ago ago

How is the diameter of these coils measured? I have a coil but am not sure what size it is.

Asked by J. Martin

The size of the coil is the inside diameter of the coil. For smaller coils it can be a bit tricky to measure by if you take your ruler you should be able to measure straight across from the inside to the inside of the spiral. Coil is measured in millimeters so make sure you have a metric ruler for your measurement.
