Silver Wire-O Twin-Loop Binding Spines

Upgrade your documents with a clean, professional finish using our Silver Wire-O Twin-Loop Binding Spines. These premium metal wires are ideal for offices, print shops, and anyone looking to create high-quality books, reports, presentations, or planners.

Wire-O binding offers a durable and semi-secure hold. Once bound, pages cannot be removed without cutting the spine, ensuring your content stays protected. Pages also lay flat when opened and can rotate a full 360°, making these wires perfect for notebooks, journals, manuals, planners, and calendars (when paired with calendar hangers).

Pitch Options & Sizes

Wire-O spines are available in two pitch formats:

• 3:1 Pitch – 3 holes per inch
• 2:1 Pitch – 2 holes per inch

How to Select the Correct Size

1. Lay your stacked pages flat (do not compress).
2. Measure the thickness along the binding edge.
3. Add 1/8" to your measurement to determine the recommended wire size.
