Commonly known as "double loop" binding, Wire-O®
binding from Pittsburgh Binding is an attractive and sturdy binding option. Using pre-formed wire loops bound in pairs down the spine, Wire-O® binding is commonly used for a wide range of published materials that include cookbooks, calendars, and user manuals.
An advantage of Wire-O® bound books is that they lay flat when open, making them ideal for items such as manuals or notebooks.
Pittsburgh Binding can handle your large or small Wire-O® binding jobs with our automatic and hand-fed wire inserting machines. We can bind from 3 or 4 sheets up to books 7/8 of an inch in thickness.
