For bulk wire binding in your large print or binding shop, buy blue 2:1 Wire-O Twin-Loop Binding Spool at Binding101. We offer only the highest quality double-o wires from James Burn, available in a huge selection of sizes and colors to fit your exact needs. Whether you need small 3:1 pitch wires or large 2:1 pitch wires, we stock the wire spools that you need.
The premier choice among professionals of all kinds, Wire-O binding offers a clean finished look that can be found on journals, notebooks, presentations, guides, and so much more. The attractive metal finish looks expensive when compared to plastic bindings, so you are sure to impress your customers. They are built to work with a large variety of industrial and automatic binding machines on the market today. When paired with these machines, twin loop spools offer a very fast and convenient way to bind large quantities of wire bound books.
Choose from many beautiful metal colors, including black, white, silver, pewter, blue, green, red, and more. Books bound with wire spools lay flat when open, and offer a full 360° flip capability, so you can flip the pages over all the way until they touch the back. This makes them a popular choice for calendars, especially when paired with our easy-to-use metal calendar hangers.
Wire-O spool is measured by a loop count, and the loop count will vary depending on the wire diameter selected. For example, the smallest 1/4" wires feature 90,000 loops on one spool, whereas the largest 1 ¼" wires feature 2,900 loops. You can use the chart below to not only see the different loop counts per spool, but also to help determine the best diameter size for your particular needs, based either on an approximate sheet capacity or approximate book thickness.
Wire-O Binding Capacity Chart:
Simple steps to get the proper fit for twin loop wire binding.
- Take the book being bound and lay it flat on a table
- Don't compress the paper and measure the thickness of the binding edge
- Take the measurement and add 1/8" - that will be the size of the binding element
* Note: the capacities listed below are approximations, determined using standard 20 lb. bond copy paper; the actual sheet capacity will vary depending on the materials being bound.
|Wire Diameter||Pitch (Holes per Inch)||Sheet Capacity*||Book Thickness||Loops / Spool|
|1 ⅛"||2:1||211-235 Sheets||1"||4,000|
|1 ¼"||2:1||236-260 Sheets||1 ⅛"||2,900|
