STEP 8
Lift the rack up onto the truck bedrail. Loosely attach the front legs to
the secured FRONT FOOTPLATES as shown in STEP 7. Position the REAR
FOOTPLATES against the bedrail. Attach the REAR FOOTPLATES to the
truck bedrail using bedrail clamps as shown in the illustration.
Note: If you prefer to mount the FOOTPLATES by drilling 3/8" holes through
the truck bedrail, locate the FOOTPLATES as per above, and attach using
included fasteners V, U, and R. We recommend using the pre-drilled hole at
the rear of the FOOTPLATES. You will have to locate and drill a second 3/8"
hole in the FOOTPLATE, as close to the leg as possible.
