  • Mark documents permanently - Do away with half impressions of faint markings that can further fade with time. Our 400 series perforators provide clear and permanent perforations for all types of documents. Your efforts are complete and irreversible.
  • Enhance office productivity - Hand stamping invoices is both time consuming and fraught with potential error. Our 400 series perforators mark documents quickly, perforating up to 25 items at a time. Even temporary staff can mark thousands of documents per hour effortlessly.
  • Eliminate duplicate payments - Our most popular application! One duplicate payment is one to many! This can occur for a variety of reasons: Invoices sticking together during the payment process, a faint ink impression, etc. etc.. Our 400 series perforators can perforate many invoices at one time, providing a permanent and obvious mark of payment having been made.

The 400 Series perforators are an affordable alternative to hand perforators, the model 400A is the answer to special heavy duty applications. If the quantity of documents of paper to be perforated is a concern, the 400A is your solution. Fixed perforations on one, two, or three 10 character lines can be quickly fabricated.
