box as possible with clamp orientation that
provides best grip, turn nut nger tight, then
use 1/2" wrench to tighten.
IMPORTANT: To keep side rail secured
on truck, ensure clamp teeth engage
grooves on side rail.

to front of box as possible
NOTE:Images below illustrate clamping options. Option A depicts standard clamping
orientation lower on the rail. Option B depicts alternate clamping orientation with half of
clamp assembly rotated 180° to provide better grip at top of rail.
H. Verify side rail is level. If side rail is not level, perform one of the following:
If side rail tilts up: loosen and lower clamp, engage teeth and then retighten clamp.
If side rail tilts down: loosen and raise clamp, engage teeth and then retighten clamp.

1st Clamp
NOTE: For trucks with electric tailgates, cover and tailgate should remain closed after
installation for at least 24 hours. During this time period vinyl ap typically conforms to
tailgate allowing electric tailgate to function properly. If interference occurs after this time
period, raise side rail at rear slightly above tailgate.
K. Repeat Step 1 to install side rail on opposite side.
L. Torque all clamps to 20 ft-lbs or value specied in special instructions (if supplied).

NOTE: For best adhesion, ensure air and
surface temperatures are above 60° F.
NOTE: With a spray-in bed liner, better
adhesion is possible by smoothing surface
and applying an adhesion promoter.
A. Ensure bulkhead is clean, wipe top surface
with alcohol pad. Clean top
of bulkhead
B. Peel protective backing as you go, align
and adhere seal gasket at one corner across
box to opposite corner and cut to length.

5: INITIAL OPERATION AND ADJUSTMENTS
A. Unroll cover and place rear bar into
strikes on side rails. Press down on rear
bar to close (20-30 lbs pressure). The
cover fabric may be tight. Over time, under
tension, it will conform to its hardware and
loosen slightly. If rear bar is too hard to push
down, adjust tensioners equally as needed
to close.
NOTE:If cover is too tight, it may impact
latching mechanism.
Strike at rear
B. Close tailgate slowly, top of tailgate
should t snug under rear bar. If cover
impedes normal tailgate operation, raise
side rails by: loosening rear clamps,
adjusting side rail up and then tightening
clamps. If there is a gap between tailgate
and cover, adjust side rails lower.
IMPORTANT: Verify each clamp is
torqued to 20 ft-lbs or value specied in
special instructions (if supplied). Start
behind cab and work toward tailgate.
C. Check cover tension by releasing latch
and then opening and closing rear bar
several times. It should snap when closing.
Cover fabric should be tight without sagging
between the bows.
D. If adjustment is needed, roll cover open
then either: turn tension adjuster clockwise
to loosen or turn tension adjuster counter
clockwise to tighten. Ensure to adjust
tensioners equally.

Turn Clockwise
To Tighten Cover
Turn Counter

E. Always seal both sides of cover with hook
and loop system. For detailed operating
instructions see pages 12 and 13.
Tip: Reasons to keep cover tight:
1. Increases longevity
2. Decreases noise
3. Enhances appearance

TROUBLESHOOTING
PROBLEM SOLUTION
Cover too loose Turn both tension adjusters counter
clockwise to move front bar forward (see
Step 5D).
Cover too tight Turn both tension adjusters clockwise to
move front bar back (see Step 5D).
Gap between rear bar and tailgate Side rails set too high (see Step 5B).
Top of tailgate hits rear bar when
attempting to close
Raise side rails at rear of box until
tailgate closes without pushing rear bar
up (see Step 5B).
Cover too narrow Check if side rail is level. If side rail tilts
up: loosen and lower clamp, engage
teeth and then retighten clamp (see Step
1H).
Cover too wide Check if side rail is level. If side rail tilts
down: loosen and raise clamp, engage
teeth and then retighten clamp (see Step
1H).
Lopsided cover (too much on one side) Check if front bar is centered between
side rails (see Step 4E).
Manual Slide Lock (on both sides) too
loose or too tight
Use 1/8” Allen wrench to tighten or
loosen set screw as desired. Slide Lock
performs best with some friction.
