1. Attach vehicle specific bracket to adjustable mounting bracket. 1 1/2” Allen drive screw must be placed “underneath” djustable
mounting bracket (See Figure 1). Allen drive screw will be accessible through hole in front of adjustable bracket. Square nut
must be placed in front of vehicle specific bracket. Place 1/4“ lockwasher between square nut and vehicle specific hook
bracket. See Figure 1 for details. To hold bracket in place, use provided hardware: 1 flat washer, 1 lock washer and 3/8” Allen
drive screw per slot (as shown in Figure 1).
2. Attach mounting brackets to bar using the carriage bolts pre-installed on the bar. Use two lockwashers and a acorn nut per bolt.
Leave acorn nuts loose so that the bracket has the ability to slide to fit your specific vehicle application. When choosing the
placement for the mounting bracket, consider the cable routing and the risk of pinching wires or anything that can lead to cable
failure. See Figure 2 for details.
3. Position bar on roof about center line of “B” pillar. Determine final location of adjustable mounting brackets for vehicle
application and ensure bar is centered about brackets and vehicle. Determine and mark off locations for mounting screws
through vehicle specific bracket into roof. Determine location for wire entry into vehicle.
4. Determine the height of bar in relationship to the roof that best suits your application. Height of bar can be adjusted by
loosening 4 allen drive screws that fasten pivot arm to either end. To simplify this procedure we recommend cutting 2 wood
blocks to your preferred height to set gap height between roof and bar. Also be sure that adjustable height bracket feet are
sitting flat on vehicle roof. See Figure 3.
5. After position of bar is determined. Tighten tilt and height adjustment screws (shown on page 5). Also tighten acorn nuts
attaching adjustable mounting bracket to bar.
6. Drill 4 holes using a #30 (.128 dia.) drill bit on each side of vehicle that were marked in Step 5. Be careful not to damage
weather stripping on vehicle.
7. Using 1 1/4” hole saw, drill hole in marked location on roof for cable routing. Be mindful that you do not drill through any roof
support members or interior head liner. Clean and debur hole.
8. Secure each vehicle specific bracket by using 4 supplied #8 x 1/2” truss head screws.
9. When required, adjust front to back tilt to make bar parallel with road for best optical range. 5/32“ allen drive adjustment
screws are located above each mounting foot in the mounting bracket base. Adjustment screws must be turned
counter-clockwise to raise either front or back of bar.
