The Dahle 20434 is designed to be used in a small office or by a team of employees for the destruction of top secret documents. It features electronic sensors that will turn the shredder on when you’re ready to shred and turn it off when the shred compartment is full or open. It’s these state-of-the-art features that save you time and take the burden out of shredding your documents. This shredding machine uses a matched pair of solid steel cutting cylinders that are capable of reducing a single sheet of paper into over 15,500 tiny particles. These particles are so small that they have been rendered impossible to reassemble. It recommended that the shredded paper also be stirred to protect security and mitigate risk.
