Condition
Some customers may comment that the roll up soft tonneau cover is too loose, or that the tonneau cover latch is disengaging and not staying closed.
Two improvements have been implemented since the original release of the tonneau cover. Be sure that the tonneau cover meets the criteria of
the items below.
Cause #1
The condition may be caused by improper installation of one or more of the upper side rail clamps. Using the outer groove (1) when a molded bed rail
protector IS NOT installed may cause a gap (2) between the pad and pickup box. This may also prevent proper latch retention.
