(Same for each side)

See the stickers located on each side rail
for clamp position, or refer to the

Longer Clamps

Some trucks use different sizes of clamps to fit curved

sidewalls. Longer clamps go in the forwardmost

(Cab) positions while the shorter clamps hold the

rails at the rear (tailgate) end.

Insert side rail

way into rail.

Place the rail assembly over

the side of the truck box.

Center rails evenly between

cab and tailgate.

(NOTE: Some applications have

rubber risers (rectangular rubber

pads.) A riser must go toward

tailgate. Some applications will

have a riser at both ends, (most

have no riser).
