Product Description

This Wire-O 3/8" Black 3:1 Pitch Double Loop Ring Wire Spool offers an attractive and professional metal finish in many sizes for books. It can bind up to 11-25 sheets of 20lb paper or 1/8" thick books. This wire binding spool is ideal for your automatic twin loop wire binding machine. As you might know, using less expensive spool wire can cause all sorts of problems with your automated machine. Choosing this Wire-O wire spool, manufactured by James Burn, will help reduce problems with stretching that can occur with cheaper import wires. This 3:1 twin loop wire binding spool comes in a wide selection of sizes and colors. It is also available in 2:1 pitch. If you need help selecting the correct diameter for your project, take a look at the sheet capacity chart below for some recommendations based on the thickness of your books. This Wire-O 3/8" Black 3:1 Pitch Double Loop Ring Wire Spool is considered to be the equivalent of if not better than GBC and Renz's Twin Loop Wire Binding Spools. Respective equivalent Renz and GBC part numbers are RZ380BKSP and 9910038BK.
Please Note that spool wire is considered a special order item and is non-returnable.
