In cases where the standard RotaChock won’t fit the available space between the machine and the foundation, the RotaChock SL probably will! With an overall height starting at only 20mm or 13/16” the slim line version will suit most of the retro-fit applications while still offering an adjustment range of 10mm or 3/8”.
