Rainflaps are only installed in the
wing sensor brackets and are not
installed for 120’ booms.
4. Insert one side of the rainflap rod into
the pre-bent hinge tab on the sensor
bracket. (Figure 6)

with the unbent hinge tab. (Figure 7)

6. Bend the hinge tab inward over the
rainflap rod until the hinge tab fits
securely in the detent groove on the
backside of the sensor bracket. (Figure

7. Ensure the rainflap actuates smoothly
when the bracket is turned upside down
and returns to the open position when
the sensor bracket is returned to its
operating position (sensor pointing
downwards toward the ground).
General Mounting Rules for Low
Profile Brackets:
A. Minimize the distance between the bolts
to prevent bending the bracket and
prevent the bracket from loosening
over time.
B. Ensure the bracket is mounted tight
against the bottom of the boom,
minimizing the distance between the
boom structure and the angled flange.
