STEP 1: INSTALLING COVER SIDE RAILS
NOTE: Some installs require special
instructions. Follow the special instructions
for rail attachment along with these
standard instructions.
A. Position side rail with weather strip
against inside lip of box and front
catch towards front of box. Push rail
forward until it touches front of box.
B. Ensure each half clamp has a wide
and narrow offset positioned at top
and bottom. Adjust top of rail flush
with top of box, hold with assistance
of another person or spring clamp.
Install first clamp as close to front
as possible and use 1/2" wrench to
tighten. IMPORTANT: To keep rail
secured on truck, ensure clamp teeth
engage grooves on rail, turn nut finger
tight, use wrench to finish tightening.
C. Check if the rail is level. If rail tilts
up, loosen clamp; lower it; engage
teeth; and retighten. If rail tilts down,
loosen clamp; raise it; engage teeth;
and retighten. For further leveling
capabilities, clamp assembly may be
rotated 180°.
D. With rail flush with top of box, install
two middle clamps equally spaced
from front to rear. At rear of box,
place rear clamp as close to tailgate
as possible, always make sure teeth
engage grooves on rail. Repeat Step 1
to install rail on opposite side. When
done, make sure all clamps are
torqued to 20 ft-lbs.
