  • S5! Attachment Frequency

    How do I determine the frequency of the S5! attachments for my roof? I have a Midwest Manufacturing 26 gauge steel roof which is compatible with the S5! "S-5-N Mini" clamps. I purchased enough clamps for mounting at every other seam location and boy do these things have a positive mount and seem to hold like crazy. My roof has 16" seam spacing. Anyone have experience with similar standing seam attachments?

    -2 rows of 11 & 1 row of 12
    -Unirac Standard racking
    -8/12 pitch, standing seam steel roof

    Thanks Butch. I'm in Minnesota so no special hurricane requirements here. I agree, the weak point is probably always the roof attachment (with standing seem metal roofs). All I can find on the S5 website is here:
    https://www.s-5.com/products/solar-s.../installation/
    but, of course, they defer to others to determine whether or not an attachment every seam is required or not. But it's still a pretty good document.

    I'd love to hear feedback if anyone has experience where they have seen these attachments used every rib vs. every other.
