Straightline Action, The 2011 Hustler II offers the same triple counter balance system and 2-cylinder twin drive vertically engaged gear system as the 2023. This ensures a vibration-free reciprocal stroke for smooth, ultra fine sanding. The 2011 Hustler II also offers a mid sized, 11" pad for sanding areas slightly larger than the 2023 but smaller than those where a 2000 Hustler would be recommended. The 2011 Hustler II comes standard with a PSA pad designed for the use of 2 ¾" abrasive rolls. An 11" hookit pad is also available.
