Remove plastic film from the canister.
Final notes: Open and close the cover to ensure it is rolling without rubbing or binding. Remove any remaining plastic
film. Be sure that all clamps and/or bolts are tight. Clamps must be periodically checked for tightness. The top surface of the
rails should be level. Loosen clamps or bolts, adjust the rail, and tighten if needed. On some models, a better fit over the
tailgate may be obtained if the rear of the rails are slightly tilted up or down.
Remove clamp and turn both of the white nylon adjustment
screws, using a 6 mm Allen wrench. One complete turn of
adjustment screws = 1/16” of adjustment.
Pull the cover closed and latch.
If there is less weather-strip exposed on one side,
adjust that rail towards the cab. Replace and tighten
the clamps and close the cover. Check again for equal
spacing at the front and readjust if needed.
STEP 7: Adjust the distance between the rails
STEP 8: Assemble and install drain tube
*Rails too far apart *Rails too close =
= clockwise counter clockwise
Some models do not use adjustment screws.
Refer to the appropriate manual section for
proper adjustment instructions.

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.
You can check for proper fit between front
cover and rolling cover
