Installation Manual

NOTE: Plastic bed liners may have to be cut or notched at the front of the bed if they touch the rolling canister. A

jigsaw with medium tooth blade, Dremel™ or RotoZip® tool works well.

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.

Using a 9/16” or 1/2” wrench ( depending on your

clamps), tighten clamps.

When attaching rear clamps, push down on the rail as

you tighten the clamps for a better seal on the pickup

box rails.

The rear of the rail may need to be tilted up or down

for best fit over the tailgate.

Some models do not use clamps. Refer to the

appropriate manual section for proper mounting

instructions.

Measure the distance at point A (above front cover).

Then measure at points B and C (above the clamps), they

must be the same as point A.

The rails must be parallel, if not then adjustments

are needed, proceed to step 7.

If parallel, proceed to step 8.

STEP 5: Install the front & rear set of clamps

STEP 6: Measure and record the distance

between the rails
