Worked great for us on a steel over steel barn.  One problem we had is the
trusses were pre-drilled with too-large holes right where we wanted to
fasten.  We carefully displaced the attachments slightly to miss the
existing holes.

Wrenches,



Anyone out there have any experience attaching arrays (from the topside) to
roofs with steel trusses under plywood decking? We’ve got a new project
that has steel trusses and we would prefer to not have to spend time in the
attic bolting through  (it was 113 degrees here today)… Is there a
fastening system out there that anyone has experience with?



Oh, the roof is composite/strengthened clay tile as well.



Thanks!
