Product Description

These high quality Black 3/8" 2:1 Pitch Twin Loop Wires are some of the best wire binding spines on the market today. Also called Wire-O, WireBind, and Double Loop Wire, these black 3/8" 2:1 pitch elements let pages lie flat with 360 Degrees rotation for convenient note-taking and photocopying as well as provide a permanent bind to your documents--meaning your pages stay secure and protected. Not only that, but these black 3/8" 2:1 pitch wire spines look a tad more refined than a plastic comb or spiral coil. Measuring 3/8" in diameter, these black twin loop wires can hold approximately 50-60 sheets. These black 3/8" 2:1 pitch twin loop wires come open in a "C" shape, allowing you to insert the spines into your punched pages and then simply use your wire binding machine or wire closer to finish your books. Product number W380BK21.

Welcome to MyBinding video. This is everything you need to know about Twin Loop Wire. First there are sizes ranging from 1/4 of an inch to 1 1/2". There are many sizes of wire, which can hold up to 300 pages. And a great benefit to twin loop wire is that pages lay flat. Better yet, it folds nicely back to back. There are 2 standard pitch sizes: 2:1 and 3:1. 2:1 is better for larger size books while 3:1 is better for smaller ones and there are custom pitches for when you find yourself with a different punch. The standard length of wire is 11 inches and again there are custom lengths for when you need it. And like most bindings, there are several different colors to choose from. It is important that your wire works with your punch and wire binding machine. First check what type of wire your machine uses before purchasing and that is twin loop wire.

Thank you for your question. The sizing guide table is based off of 20 # stock for other weights of paper that you would want to base the size of the spine on the physical thickness of the completed document. A good rule of thumb would be to add 1/8" to the size of your completed document to determine the size of the spine that you would want to use.

You are probably going to want to choose 5/8" wire if you are using 20lb bond paper. However the best way to know for sure is measure the thickness of your book including covers and add between 1/8" to 1/4" to the measurement. This will allow your pages to turn freely and will ensure an awesome fit no matter what thickness of paper you are using.
