Product Description
This Wire-O 5/16" Black 3:1 Pitch Double Loop Ring Wire Spool has a sleek, high-quality metal finish, and it comes in a wide range of convenient spool sizes. The maximum thickness of a book it can bind is 1/8", which is approximate to 11-25 sheets of 20 lb paper. This twin-loop automated wire binding spool is the perfect fit for your machine. You may already know that your automated machine might experience various issues if you utilize certain spool wires. This James Burn-made Wire-O wire spool is a good option for avoiding the stretching issues that often arise when using less expensive imported wires. This spool of 3:1 twin-loop wire binding is available in many different sizes and colors. The pitch can also be changed to a 2:1 ratio. Below is a sheet capacity table that will help you choose the best diameter for your project depending on the thickness of your books. To many, the Wire-O 5/16" Black 3:1 Pitch Double Loop Ring Wire Spool is on par with or perhaps superior to the Twin Loop Wire Binding Spools sold by Renz and GBC. Wire binding spools come in many shapes, sizes, and colors. Black, white, silver, pewter, blue, green, and other professional hues are available for your first color choice. Next, figure out what size wire you need. If you need help deciding what diameter to use for your project, the capacity table provided below can give you some ideas based on the thickness of your books. According to the size you select, the pitch will be set automatically. Smaller sizes, from 1/4 inch to 9/16 inch, don't have a 3:1 pitch like the larger ones (5/8 inch to 1-1/4 inch). Need the wire trimmed to size? Yes, no problem! Visit our custom wire page for more details on our wire binding spines.Product Details
