DuoMac-421 Combo Coil 4:1 & Wire 2:1

The unique DuoMac-421 is a dual purpose punching and binding machine combining both wire and coil binding in one space-saving unit. Using two independent die sets, this heavy-duty manual punch can punch holes for 4:1 pitch plastic coil and 2:1 pitch double-loop wire binding. Each die set has a single punching capacity of up to 20 sheets of 20lb paper, and is open on both ends for handling larger sized documents. All wire die pins and five coil die pins can be disengaged, giving the operator precise control over which holes will punch and avoiding partial side-end perforation. The DuoMac-421 features side and depth margin controls and a built-in paper scale. An integrated wire closer, which can close wire up to 1-1/4" diameter, uses a continuous adjusting scale for an exact and secure closure every time. Coil crimpers are included free with the punch; an electric coil inserter can be purchased separately. Made to high-quality specifications, the heavy-duty DuoMac-421 has multiple binding capabilities and can punch and bind a wide variety of documents.
