<DIV><SPAN class=312590421-21042011><FONT face=Arial>I'm proposing a PV array on
a metal building with L feet attached directly thru the roof into
the purlins. The plan is to use thread cutting SS bolts, a minimum of ¼-28
pitch. The metal is 14 ga and will engage over 2 full threads and
because the array is only 2 landscape modules on NS rails there will be 2
bolts for every module. 36 total. Im using a mag base drill press so the144
holes will be straight & round. </FONT></SPAN></DIV>
<DIV><SPAN class=312590421-21042011><FONT face=Arial>What surprises can I expect
or is there an easier way to go about this. Your 2¢ is welcome.
