These Blue Spiral-O 19-Loop Wire Binding Spines are twin-loop wires that are made in a plastic comb binding pitch, creating a total of 19 loops across a letter size 11" binding edge. This means they can be used with your plastic comb punch to create a more professional looking document than traditional plastic combs. Spiral-O wire combs are available in several sizes from 1/4" up to 1", so you can bind documents as thin as just a few pages, up to about 210 sheets, depending on the paper stock. They are packaged with 100 bindings per box, and are available in 4 stocked colors, including black, white, silver, and blue.
How to Bind with Spiral-O Wire
   ① Punch your pages with your plastic comb punch machine (or use pre-punched comb paper)
   ② Insert Spiral-O wire into the holes
   ③ Close the wire with a wire closer (such as the Durawire)

With Blue Spiral-O 19-Loop Wire Binding Spines, you can produce professionally bound wire documents using your standard plastic comb binding punch machine or pre-punched comb paper. They have the clean look of traditional twin-loop wire bindings, but with a unique loop spacing that allows them to fit into 19-hole plastic comb punched pages. This means that you can use your comb machine to produce premium bound wire documents with Spiral-O wires! All you need is a wire closer to complete the bind, and you're done! No need to invest in a new punch machine.

Spiral-O wires are packaged with 100 spines per box, and are conveniently separated with chip board strips to keep the spines from getting tangled. They are available in sizes from small 1/4" diameters for a maximum of about 25 sheets*, up to 1" diameters for a maximum of about 210 sheets*. Choose from several classic colors, including black Spiral-O, white Spiral-O, silver Spiral-O, or blue Spiral-O. All sizes and colors are 11" long for your letter size documents measuring 8 ½" x 11", and feature 19 double loops.
