<p>Ray,</p>
<p>It appears that there is something between the module frame and
rail that may have introduced the frame crack. Perhaps as it was
tightened, and not due to the wind. What is the light material
that looks like it is sandwiched between the module and rail?<br>

<p>Here's another mount at the edge of failure, from the same
system. Hardware is tight. Like many, I had lots of love for
good ol' fashion bottom mounting vs top mount, until this
happened about 5 years ago. <br>

<p>I've had several modules pull off of bottom mount racking in
high winds, but never top mount racking. Newer modules have
much thinner frames, but are much more surface area than the
old days. </p>

and for the life of me I don't understand the logic of of a
