The ONYX 4000PLUS is an 11-inch (A4) open-ended punch binding machine for use with a comb, wire, coil or spiral book binder that features the EZ operator changeable dies. With a paper punching capacity of 20 sheets of 20-pound (80 gsm) bond and a very reasonable price, this punch makes manual punches obsolete.

With a three-year warranty, and a very competitive price, no other solution in its class can match its price performance!
