These Professional Grade Shredders are designed to be centrally located in the office. Centralized, at-the-source shredding is more secure and cost-effective than using an outside shredding service. Varying feed openings depending on the model can handle a wide range of document sizes and a variety of cutting heads are available that offer different levels of security. All Centralized strip-cut and cross-cut models will accept staples and paper clips and many will shred CDs.
