Wire-O BindingAKA: twin-loop, double-loop, duo-wire, double-O

Wire-O Binding is similar to spiral coil binding but looks more solid and upscale. Wire-O binding works with books or documents with multiple pages and inserts such as index tabs or section dividers.

Wire-O binding consists of pre-formed pairs of wire loops inserted through holes punched through a book’s cover and internal pages. Crimped together to form an “o”, the wire loops bind the cover and pages firmly while enabling the pages to open without restraint.

Wire-O Binding Advantages

• Books open 360 degrees (cover to cover) – they can lie flat when opened and can be flattened from any page.
• Left and right pages open symmetrically so that material crossing two pages (maps, charts, graphs, illustrations) can remain aligned.
• Books can be wrapped from any page, taking up half the space.
• Pages turn easily.
• Looks nice!
