[RE-wrenches] S5 Clamps

[Michael Kelly]

Joel,

I have an upcoming project where we are contemplating this very
install: S5 clamps without rails.  I would also like to hear the
disadvantages, and any experience others have had installing this type
of clamp onto a standing seam.

Thanks,
Mike

The obvious advantage is lower cost, but are there any disadvantages? If you used S5 clamps without rails, did you have to get a licensed engineer's wind-loading structural analysis? Thank you very much for your advice.
