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.  Insert  the  tension  bolt  through  the  mounting  strap  and
anchor  plate,  into  the  tinnerman  nut.  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 40in./lbs.

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.

Insert foot into extrusion with locking plate
attached.
