Each cleat must be located and tightened down in one of
the detents, along either rail, in order to keep cargo
properly secure.
To move the cleat to any position on the rail, turn the nut
counterclockwise, approximately three turns. Then pull
out on the cleat and slide it to the detent nearest the
desired location. Make sure the cleat is seated in the
detent and tighten the nut.
