FAQ
Frequently Asked Questions
No, it is a regionalism almost exclusively used and understood in Canada. It is very uncommon in other English-speaking countries.
A duo-tang has flat metal fasteners that pierce the paper, typically along a central spine. A binder (ring binder) has rings that open and close to hold pre-punched paper.
It is best avoided in formal international contexts. In Canada, it is acceptable in school-related contexts. For formal business or academic work outside Canada, use terms like 'presentation folder' or 'report cover'.
It is derived from the trademark 'Duo-Tang', which likely references the 'two' (duo) metal 'prongs' or 'tangs' that fasten the papers. The name became genericized in Canada.
