With a clean, compact design, the OffiWire-21 manual wire binding machine provides a perfect solution for any low volume, wire binding operation. This dependable unit combines a punch that can punch up to 10 sheets of 20lb paper at a time and wire closer that works with 2:1 pitch wire sizes from 5/8" to 1" diameter. Hardened steel dies deliver a clean, precise punch even when working with hard-to-punch materials such as PVC - the "U" shaped handle aides the punching operation for effortless perforation. The bilateral closer systematically adjusts independently at each end for even closure of the wire while a side margin guide allows for holes to be evenly centered on the document. This effective design, along with its durable metal chassis makes the OffiWire-21 stand out as a practical and economical wire binding answer for any low volume situation.
