The Swingline® LX20-30 cross-cut shredder is made for heavy usage. Ten or more people can shred up to 20 sheets at a time continuously into a 30-gallon pull-out frame that can be lined with Swingline® paper or plastic shredder bags (sold separately) to make disposing of shreds easier. This model also shreds paper clips, staples, credit cards, CDs and DVDs. The included self maintenance features such as Non-stop Jam Free™ technology, Intelligent SelfOil™ and Intelligent Self-cleaning cutters make this shredder easy-to-use and keep up with. While shredding, a green light indicates if you are within the shredders capacity. A red light indicates you are feeding too many papers at once and the shredder may jam. The cutters auto lubricate and clear any small, stuck shreds after each use. Super cross-cut shred style provides the reliable, Level P-4, document security that any large office with confidential shredding needs demands.
