Shredding was never easier with Swingline's New Stack and Shred 750M. Simply lift the lid, insert a stack of documents and shut the lid. The Stack and Shred 750M shreds automatically, hands free. By eliminating the need to manually feed papers, you can work on other tasks while the shredder shreds for you. The 750M automatically shreds as many as 750 sheets, including those fastened with paper clips or staples.. This hands free shredder has a locking feature to keep your sensitive items safe during the auto shredding process. Once shredding starts, the paper chamber locks and cannot be opened unless a user enters their 4-digit PIN code to interrupt shredding. Only once the shredding process is complete will the shredder unlock for its next load. For shredding of DVDs/CDs, credit cards, glossy and folded sheets a manual shredding slot is also included, which shreds up to 10 sheets at once. The 750M is a micro-cut shredder, delivering Level 5 high security that is suitable for shredding confidential documents including sensitive financial and personal identification information. One sheet of paper is shredded into approximately 2000 pieces and caught in a 31-gallon waste bin. The Swingline Stack-and-Shred 750M Hands Free Shredder is an innovative, automatic shredder that simplifies shredding and helps increase your productivity level.
