Figure 4-19.

IMPORTANT: Only M6 Fingers fit in the bottom row. All M3 and M1 finger cover plates have extended lips at front. This extended lip will not allow these fingers to be installed in the bottom row.

IMPORTANT: When inserting fingers the tab on the outer plate must be in the groove as shown in Figure 4-20. There is a blocking tab on the outside of the groove which will prevent inserting the finger in the groove if the outer plate is moved away from the flange of the finger manifold.
