With its sleek modern design, the OffiWire-31 manual wire binding machine is perfect for all low volume, wire binding requirements. This reliable unit includes both a punch and wire closer that can punch up to 10 sheets of 20lb paper at a time and works with 3:1 pitch wire sizes from 3/16" to 9/16" in diameter. Hardened steel dies deliver a clean, precise punch even when working with hard-to-punch materials such as PVC and the "U" shaped handle amplifies punching strength for ease of perforation. A bilateral closer independently adjusts at each end for even closure of all wire sizes while a side margin guide allows for evenly centered documents. The efficient design, coupled with a strong metal chassis and quality components makes the OffiWire-31 stand out as a practical and economical wire binding solution for low volume users.
