Destroyit® Centralized Office shredders are heavy-duty, high-volume machines specifically designed to shred large amounts of material daily. Ideally, they are positioned in a common area, such as next to a copier or fax, and shared by a number of employees. Centralized, "at the source" shredding is more secure and cost-effective than using an outside shredding service. Feed openings from 10 1/4 to 16 inches handle a wide range of document sizes and a variety of cutting heads are available in 6 security levels. All Centralized strip- and cross-cut models will accept staples and paper clips and many will shred CD's.
