Is ideal for manuals, workbooks, and catalogs. It is frequently employed in:
- Learning environments
- Reference intensive documents
- Consulting materials
- Field Installation Manuals

Wire-O’s double metal loops:
- Allow a book to open flat
- Enable the book or manual to fold completely in half
- Keep pages in horizontal alignment across the binding

- Bind thickness from 3/16” (5 mm) to 1 1/4” (32 mm)
- Standard color is black, other colors available
- Page counts from 48 to 600

Wire-O, lacking the memory of plastic, will deform if subjected to excessive weight, twisting or bending.

The external, round binding, extends beyond the text edges, creating a non-flat packing shape and increasing space requirements.
