Additional Information and Adjustments
The web loops on the Tonneau are to help with removing the Tonneau. They can be tucked into
the utility channel when not in use.
The elastic Tie Down Straps on the Tonneau and the Tie Down Straps installed on the Rear
Tailgate Bar are provided to secure the Tonneau and Tailgate Bar when the fabric is folded up.
If the Tonneau fi t is too loose, either:
– move the front rail slightly forward, or
– spread the side rails slightly.
When using the BestRail™ Soft Tonneau, the exterior channel is still accessible for the Be-
stRail™ Overhead Rack System (42791), the BestRail™ Tie Down Anchors (42973) and the
BestRail™ Retractable Tie Down System (42794).
