extensions are offered in two lengths (3/4”and 1-1/2”). The longer extensions areprovided to prevent interference issues that
may occur between the actuator motor and
the legrest receiver (not shown) as a result of
height adjustments to the knee pivot point
(mounting pin height). The various pin
adjustments (pivot points) are illustrated
below in Figure 5B.
