1 Assemble rail end caps Assemble latch stops

Insert the 5/16-18 x 0.500 bolt (B) through the hole in
the bottom of the rail end cap. Start threading the
5/16” nylon locknut (C) onto the bolt but leave loose.
Repeat on other rail end cap.
3 Assemble clamps
Insert the nylon set screw
(E) into the side of the
clamp. Then insert the
5/16-18 x 1.625 bolt
or 5/16-18 x 2 bolt (A)
into the bottom of the
clamp. Repeat on all
other clamps.
Insert the 10-32 x 0.750 Torx (D) in each of the holes on
the rails until the flange on fastener is touching the surface
of the rail. The fastener should protrude slightly from the
hole on the back side of the rail. Tighten fully. Completed
best by using a driver and a T25 bit. NOTE: fastener may
be slightly difficult to insert using Hex driver handle due to
self-tapping feature of fastener.
Place canister assembly onto truck bed rails
right behind the cab. Center canister assembly
across width of truck. Locate holes on underside of rails and
slide each rail onto respective canister tab.
Insert the 5/16-18 x 0.500 bolt (B) through the hole in
the bottom of the latch stop. Start threading the 5/16”
nylon locknut (C) onto the bolt but leave loose.
Repeat on all other latch stops.
4 Assemble cover on truck bed
NOTE: The front cover weather-strip must lay flat across the truck
bed. Make certain it is pointed towards the cab. If it extends past
the bed rail cap, trim to fit right up to the cap on truck bed.
For GM models, insert
the bolt (A) through lock
washer, then through
clamp (F). Finally, place
spacer on top of clamp,
as shown above.

6 Attach rail end caps and position cover
To cap off the driver and passenger
side rails, slide the rail end caps onto
their mating rail. Tighten bolt on
bottom (B) and fastener on top (I) to
lock position of each rail end cap. Do
not exceed 5 ft-lbs of torque when
tightening the bolts.
Position cover so that there is a 1/8”
gap between the truck tailgate/tailgate
protector and the rail end cap. Use the
provided 1/8” measuring tool.
1/8” gap

Rail end cap
NOTE: If all latch stops are desired, insert 2 latch stops
and 2 nylon locknuts (C) into each rail channel. See figure
above for proper order of installation. Do not worry about
the position it will be adjusted later.
3 latch stops are supplied for each rail. 2 latch stops and 2
nylon locknuts (C), used later in step 8, are required for each
rail (front and rear) in order to function properly. If less latching
positions are desired use less latch stops. Must have the
same amount in each rail.
When inserting the nylon locknuts (C) be sure the nylon portion
faces up in the rail slot.
Slide 1 assembled latch stop into each rail opening and
position it 1/16” away from fastener (D). Tighten the fastener
head on the latch stop until it does not move. Do not exceed 5ft
-Ibs of torque when tightening the latch stops.
5 Insert latch stops
( I )

7 Position the latch stops on the rails
On each rail, slide the rearmost latch stop
flush with the Rail End Cap and tighten
bolt (B) on underside until latch stop is
tight and doesn’t move.
8 Install clamps
Locate the two nylon nuts (C)
in each rail (inserted in step
5). Place clamps in channel
as close to the front and rear
latch stops as possible.
(shown to the right). Then
line up bolts with nuts in
channel. Start threading the
bolt but leave loose.
Position clamps at a location where there are no obstructions from any parts of truck bed, e.g. truck, box geometry,
plastic bed rail caps, etc. Tighten bolts so clamps no longer slide in rail channel. Repeat on opposite rail at same
location. Do not exceed 5 ft-lbs of torque when tightening.
Figure below illustrates the use of all 3 latch stops evenly spaced along the rail length.
The remaining latch stops can be placed at the customer’s desired location anywhere in the rail as long as they are in the
same position on both rails. It is crucial that these are positioned at the same place on each rail in order for
the cover to function properly.
Once the desired amount of latch stops are positioned the same in both rails, tighten the bolts (B) on the bottom of each latch
stop until they do not move. Do not exceed 5 ft-lbs of torque when tightening.

5
10 Measure and adjust rail position
Be sure rails are not tipped in or out of truck bed. Rails must
be parallel to one another in order to function properly.
Measure cover at the 3 locations shown in the image. The
measurements for A, B, and C should all be the same. Once
rails are parallel, tighten the bolt in the front face of each
clamp until clamp is secured to truck.
If adjustments need to be made loosen clamps and turn the
nylon screw in or out to achieve parallel rails. The same
adjustment needs to be made on the opposing rail. Retighten
clamps to secure cover to truck.
Once again measure the distance between the rails at
locations A, B, and C along the cover. If necessary, continue
making adjustments until rails are parallel within 1/16”.
Install drain tubes
Insert tubes into the holes in the bottom of
the canister and turn to the right. 2 clicks
means they are secured.
On some trucks there are factory drain holes in both front
corners, on others there are plastic plugs that can be
drilled out for the tubes. You can enlarge existing holes or
drill new holes in the front wall or floor if needed. Be
careful of what is behind when you drill. If using a plastic
bed liner, then holes can be drilled through the liner only.
Cut the tubes to length to fit in desired locations.
9 Align aluminum rail
Align the aluminum rails with the spiral rail
section so that they are in a straight line (see red
line on image).
Then turn nylon set screw
(E) on each clamp until it
contacts the truck bed rail.

FINAL NOTES: When cover is not in use, make certain it is secured in latch stops to prevent cover from rolling.

Toyota Tundra 5.5 Ft. bed 2007-up Installation
Check the parts shown here, this model has 2 different styles of clamps and different mounting instructions.
(2) Clamps that will
be used at the CAB
end in step 8.
(2) Clamps that will be
used at the TAILGATE
end in step 8.
Continue with the instructions on page 1, then refer back to this page for STEP 8 to install the clamps.
Locate the two nylon nuts (C) in each rail (inserted in step 5). Insert the longer clamps into the rail channel first as close to the
latch stops as possible on the CAB end. Now insert the shorter clamps into the rail channel as close to the latch stops on the
TAILGATE end as possible (see picture above).
Then line up bolts with nuts in channel. Start threading the bolt but leave loose.
Position clamps at a location where there are no obstructions from any parts of truck bed, e.g. truck, box geometry,
plastic bed rail caps, etc. Tighten bolts so clamps no longer slide in rail channel. Repeat on opposite rail at same
location. Do not exceed 5 ft-lbs of torque when tightening.
