into the rail and
clamp teeth are
aligned to the rail
slots to ensure grip.

NOTE: Always apply
downward pressure
to the rail when
tightening the clamps
to ensure that the
rail sets ush and
seals properly.
Set the cover in the folded position, with the cab
panel at the front onto the rails at the front/
cab of the truck.
Before mounting the cover on the truck, using a screw driver install
the two buckle ends into the pre-drilled holes on the front header
panel. Insert the posts from the bottom, thread the screws down
though the buckle end. Do not over tighten, hand tighten,
Do Not use a screw gun.
At the front cab, fold the header panel back and insert 2 mounting bolts through the keyed slots. When closed, the two
screws will align with the slotted bracket of the cover rails. Repeat on the opposite side.
Install mounting hardware loosely
underneath the slotted bracket
on the rail. Start with the rubber
washer, then the large at washer,
then the nylon lock nut.
Install two on either side.
Leave the nuts loose for later
adjustments.
Unfold the cover toward the tailgate. Make sure
the cover ts squarely between the rails.

The cover’s aluminum frame at the tailgate should
just t inside of the tailgate when the cover is
correctly positioned from front to back.
The clearance is approximately 1/4”, 6.35mm.
The rear edge of the cover and tailgate seal should rest on top
of the tailgate. The cover must also be parallel with the tailgate
and truck bed.
Once the cover is properly aligned, carefully open the cover
ensuring that it remains in position. Tighten the four mounting
nuts. Do Not over tighten the fasteners, Do NOT use power tools.
Check that the cover operates correctly and the latches engage,
if not loosen the fasteners and realign.
Attach the drain hoses to the front drains and
route the hose through the manufacturer bed
plugs. Remove the plug or drill a 7/8”, 22.3mm
hole in the bed plug. Install hoses on both sides.
The hoses may have to run behind a drop-in
bed liner.
Check that the cover panel latches on both sides
make proper contact with the side rails.
Adjust the cover left to right so that both latches
have equal engagement into the side rails.
Check for tail panel latch engagement. Check to see that both tail panel latches make proper contact with the side rails.
If the tail panel latches do not contact properly, remove the small panel screw and slide the end cover off of the latch assembly.
Loosen the two screws (remove and re-tighten screws by hand only) and slide the latch pall assembly to contact the rail.
Check and adjust on both sides. Tighten the screws and replace the cover and cover screw.
