Loosely secure foot and locking plate.
Strap Mounting:
1. Locate the mounting foot, anchor plate and locking plate included with
your lightbar. If not already present, install the locking plate onto the
mounting foot. When properly positioned, this plate is centered from side-
to-side on the mounting foot.
2. Flip the lightbar upside-down to expose the bottom of the extrusion and
place the mounting foot onto the extrusion.
3. Rotate the mounting foot 90° in a counter-clockwise direction. Make sure
that the edges of the mounting foot swing into position under the extrusion
mounting lip. Install an anchor plate onto the extrusion in the same
manner.
4. Repeat this procedure for the remaining mounting foot and anchor plate
and return the lightbar to its right side-up position.
5. Position the lightbar onto the vehicle roof in the desired mounting location.
One often selected location is directly above the B-pillars. This area is the
strongest part of the roof. Refer to your lightbar manual for cable exit
location, to be sure that the lightbar is facing the proper direction.
6. Adjust the two mounting feet outwards so that they are as close to the
edge of the roof as possible. Both mounting feet must be in full contact
with the roof. Be sure that there is no less than 1/2” clearance between
roof and lightbar at their closest point. When the mounting feet are in their
proper position, lightly tighten the locking plate allen head set screws.
7. Return the lightbar to an upside-down position. Slide each anchor plate
outwards until it is fully engaged with its corresponding mounting foot.
With the mounting feet and anchor plates in their proper positions firmly
tighten all of the set screws (2 or 4 per side). Flip the lightbar right side-up
and return it to its mounting position.
8. Open both drivers side doors. In the area directly below the mounting
foot, pull the weatherstrip away from the vehicle so the area where the
mounting strap will be secured is exposed. Repeat for the other side.
9. Insert the mounting strap through the mounting foot. Be sure that the
strap fits flush against the area where it will be secured onto the vehicle.
IMPORTANT! The lightbar should be located a minimum of
16" from any radio antennas!
Permanent Mounting:
1. Locate the mounting foot and locking plate included with your
lightbar. If not already present, install the locking plate onto the
mounting foot. When properly positioned, this plate is centered from
side to side on the mounting foot.
2. Flip the lightbar upside-down to expose the bottom of the extrusion
and place the mounting foot onto the extrusion.
3. Rotate the mounting foot 90° in a counter-clockwise direction. Make
sure that the edges of the mounting foot swing into position under the
extrusion mounting lip.
4. Repeat this procedure for the remaining mounting foot and return the
lightbar to its right side-up position.
5. Position the lightbar onto the vehicle roof in the desired mounting
location. One often selected location is directly above the B-pillars.
This area is the strongest part of the roof. Refer to your lightbar
manual for cable exit location, to be sure that the lightbar is facing the
proper direction.
6. Adjust the two mounting feet outwards so that they are as close to
the edge of the roof as possible. Make sure that both mounting feet
are in full contact with the roof. Be sure that there is no less than 1/2”
clearance between the roof and the lightbar at their closest point.
When the mounting feet are in their proper position, lightly tighten the
locking plate allen head set screws.
7. Turn the lightbar upside down and firmly tighten all of the set screws
from step 6 (2 or 4 per side).
8. On the adjustable foot, use the hole in the pad as a guide to drill the
two holes into the mounting foot at the locations shown.
9. Place the lightbar in its final mounting position on the vehicle, mark
the mounting hole locations off onto the mounting surface, remove
the lightbar and drill the mounting holes.
10. Place the lightbar back onto the vehicle lined up with the mounting
holes and secure the mounting feet to the vehicle with the supplied
hardware.
