HD8318 18″ Wire Closer
The Rhin-O-Tuff HD8318 18″ wire closer is a precision-engineered 18-inch wire closer designed specifically for 3:1 pitch double-loop wire binding. Built for large format documents and production environments, this advanced wire closer streamlines binding into a single, efficient step.
With capacity for binding edges up to 18 inches, the HD8318 is ideal for calendars, landscape documents, and oversized presentations.
