The 2-fold grid plate 96 is very often used as a supplement to the 4-fold grid plate 96. Combining or lining up these two multiple grid plates expands the zero-point grid, creates more clamping positions and increases the contact surface on the machine table when using larger clamping devises, such as the Makro•Grip® Ultra system. With a continuous zero-point grid, the available space on the machine table can be used efficiently.
