This is the micro-cut shredded that automatically feeds up to 75-sheet stacks of paper into its blades to eliminate tedious, manual feeding. Simply place a stack of paper into the tray and the device automatically feeds up to three sheets at a time into the blades, shredding up to nearly 8' of paper per minute and leaving you free to complete other tasks. The steel blades shred paper and chop credit cards into 1/12" x 5/9" indecipherable fragments and quickly cut through staples and paper clips. If a jam is detected, the shredder automatically cycles the blades through forward and reverse to clear the blockage. The shredder also has a manual feeder that shreds up to seven pages at once, it generates only 55 dB of noise (quieter than a normal conversation), and has a 5.2-gallon removable bin. Four casters enable easy relocation. 24 1/2" H x 13 2/3" W x 10" D. (22 1/3 lbs.)
