Wire binding creates a clean, high-tech, contemporary presentation and books open a full 360 degrees, laying completely flat. It’s is also very durable and withstands temperature extremes.
Twin Loop Wire (sometimes called Wire-O binding, Double Loop wire binding or Ring Wire binding) provides a durable & professional book binding solution. This method fits into a 32-hole or 22-hole punch pattern.
Spiral-O Wire (sometimes called Wire Comb) resembles twin loop wire yet fits the 19-hole configuration normally used by GBC/plastic comb punches. This versatility allows the use of your plastic comb punch for both plastic comb & wire - requiring only a wire closer to crimp the wires closed.
