4.
Ensure that the assembly is square by taking diagonal measurements from
corner to corner.
When the measurements are equal, fully tighten the load bars to the
tracks.
Place the assembly on the truck cap or tonneau cover and position using
suggested dimensions in step 5.
7.
10.
13.
Center the bottom gasket on each track by sliding the end caps
into the ends of the track.
Place the remaining 1/4-20 x 1-½” screws through the
mounting holes and into the roof.
To gain access to the mounting holes:
Secure track to roof by tightening the screws with flanged
washers and nuts with integral lock washers.
Slide the rack anchors and tie downs together.
8.
Lift the top cover gasket on one end and note the mounting hole near the
rack anchors and tie downs.
Note the integral lock washer faces the flanged washer!
Adjust the rack anchor and tie downs so they are near to the mounting
hole.
14.
Lift up the other end of the top cover gasket until it meets the tie down.
This should give access to all mounting holes on the track.
5.
Using the remaining mounting holes as guides, drill ¼” diameter holes
through the roof.
Repeat for other track.
If necessary, cut screw to allow cap to fit properly on flanged
washer.
Temporarily secure the end caps to the track with tape. Lift the
edges of the top gasket enough to reveal both corner holes.
11.
Press caps onto the flanged washers.
Reposition the track on the roof, centering the center punch
marks with the corner holes.
Repeat steps 12 -14 for other track.
9.
15.
Remove the tracks from the roof.
Clean any debris from drilling the holes.
Inspect underneath cap or tonneau to avoid obstacles during assembly.
Place a bead of silicone around each hole on the cap / tonneau.
Suggested distance from rear of vehicle to tracks is 8” – 10” or centered as
desired.
A bead of 1 inch in diameter (25mm), 1/8” (3mm) in height and ¼” (6mm) in
width should be sufficient to seal the holes.
6.
12.
Using the corner hole as a guide, drill a ¼” diameter hole through
the roof. Slide the ¼-20 x 1-½” screw through the hole.
Remove the tape securing the end caps to the track.
Lift up the edges of the top gasket to reveal the corner holes.
Place two ¼-20 x 1-½” screws through the corner ends of the track.
Snap the top cover gasket into place.
Mark the center of the four corner holes using a center punch.
Using the two screws as guides, position the track with the temporarily
secured end caps over mounting holes.
Recheck the position of the other corner hole over the center
punch mark. Reposition if needed.
Adjust the sliding rack anchors and tie downs to desired
locations. Repeat for other track.
Remove assembly from the roof.
Place the track onto the roof.
Using the other corner hole as a guide, drill a ¼” diameter hole
through the roof and place the ¼-20 x 1-½” screw through.
Remove crossbars from tracks.
Place the cross bars over the rack anchors.
