IMPORTANT! The lightbar should be a minimum of 16" from any radio
antennas!
Permanent Mounting:
1. Locate the mounting foot and mounting plate included with your lightbar. If not already present,
install the mounting plate onto the mounting foot. When properly positioned, this plate is centered
from side-to-side on the mounting foot.
2. Flip lightbar upside-down to expose bottom of extrusion and place mounting foot onto 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 your lightbars 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 (See below). 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 mounting foot 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. Note that 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 using the supplied
hardware.

width as the vehicle roof. If too large or small it will not mount properly
and may come loose during driving.
Slide Bolt Mounting (Permanent):
1. Position the slide bolt mounting plates onto the bottom of the lightbar extrusion. These plates rotate into position the same way as the mounting foot. Position the plates as
far outward as possible (if a 3rd mounting plate is used, it should be positioned under the center of the lightbar).
2. Secure the plates to the extrusion using the set screws provided.
3. Position the lightbar onto the vehicle and mark the mounting bolt locations. Drill the necessary mounting holes using an appropriately sized drill bit sized for a 1/2” bolt.
Strap Mounting:
1. Locate the mounting foot, mounting plate and tinnerman plate included with
your lightbar. If not already present, install the mounting plate onto the
mounting foot. When properly positioned, this plate is centered from side-toside 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 a tinnerman plate onto the extrusion in the same manner.
4. Repeat this procedure for the remaining mounting foot and tinnerman 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 the roof and the lightbar
at their closest point. When the mounting feet are in their proper position, lightly
tighten the mounting foot allen head set
screws.
7. Return the lightbar to an upside-down
position. Slide each tinnerman plate
outwards until it is fully engaged with its
corresponding mounting foot. With the
mounting feet and tinnerman 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,
carefully pull the drivers side weather-strip away from the vehicle. Remove
enough so that the area where the mounting strap will be secured to the
vehicle is exposed. Repeat procedure for passenger 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. Insert the
tension bolt through the mounting strap and into the tinnerman nut on the
tinnerman plate. Tighten slightly with a long shafted, Phillips screwdriver.
Repeat procedure for passenger side.
10. If your mounting strap has mounting holes in the end of the strap, use these
holes as a template to drill appropriately sized pilot holes through the strap and
into the vehicle. Repeat for passenger side of the vehicle.
11. Firmly tighten the tension bolts to secure the lightbar to the vehicle.
NOTE: Model MKAJ is an adjustable mounting foot. On this model you may
loosen the screws on the rear of the foot and adjust the angle of the lightbar.
This feature can be used if the angle of the roof is not level with the road.
IMPORTANT: To adjust the leveling screws you must use a torque wrench set
at 35 to 40 in./lbs.
