loops in the side rails to
help secure large loads.
Reposition the tie - downs by turning them
counterclockwise, then slide them along the side rail.
Turn the tie

If you wish to attach the luggage tie - downs or other
compatible bicycle or ski accessory racks to the
crossrail, use the adjustable tapped plates under the
bumper strips.
Lift the end of the bumper strip with a flathead
screwdriver and cut off enough of the strip to access the
tapped plates.
