STEP 6: Measure and record the distance between the rails.
Measure the distance at point A (on top of the front cover).
Then measure the distance at points B & C (above each clamp).
They must measure that same as at point A, or up to 1/16", 1.6mm smaller than A.
It is important the rails are parallel, if they are not proceed to step 7.
If the measurements are correct, proceed to step 9.
STEP 7: Adjust the distance between the rails.
Remove the clamp and turn the white adjustment screws with the 6mm Allen wrench to move the rails.
one complete turn = 1/16", 1.6mm. Turn both screws.
When properly adjusted, replace the clamp as in step 5.
STEP 8: Check for proper fit between the front cover and the rolling cover.
With the cover closed and latched, if there is less weatherstrip exposed
on one side versus the other then adjust that rail more forward and toward the cab.
Loosen the claps and move the rail.
Check again for equal spacing, adjust as necessary
then tighten all the clamps per step 5.
If the rails measured to be too close together,
turn the screws counter clockwise.
A
B
If the rails measured to be too far apart,
turn the screws clockwise.
