Wire calendar hangers are small, sturdy pieces of wire that have a shallow curve located in the center and are used to transform bound documents into wall-hanging calendars. This curve is aligned with a notch on the edge of the document (which is created using a half-moon punch), and the resulting opening allows the calendar to be hung using a nail or push pin while still providing clearance for the pages to be turned. They are available in two sizes – 6” wires that accommodate calendars that are 6”-9” on the bound side and 10” wires that are designed for calendars that are 10” or larger on the bound edge. The calendar hanger is secured in place by a standard wire binding spine (recommended size: 5/16”).
