The spalling effect with larger SS hardware has caused me to return to regular plated hardware, if the project isn't near the ocean, and just use SS washers when in contact with Aluminum.<div>Having a 3/8" SS bolt grind itself to a halt before even starting to compress the lock washer, and then have it not back off is a huge time waster. Having to then cut the offending bolt off without damaging the nearby rail or modules is also no fun. All this while dangling from a harness on a steep roof, with the sun about to go away......now we're contemplating retirement.....</div><div><br><div>

We broke one hex head bolt in the middle of a rail before we learned a
valuable lesson: Always use anti-seize on any bolt you can't allow
to break.<br><br>

the top of the rail is a design flaw. They should use drop in T-bolts,
like Unirac. What happens when you break one, after installing enphase
micro's, and grounding lugs, etc. I've had to cut the bolt off, and
install an extra Unirac t-bolt. IronRidge needs to seriously rethink that
one. Other than that, I really like their products, especially the dark
bronze anodized rail. Looks great under dark framed modules.<br>

As for racking manufacturers and design oopsies, anyone have anything
nice to say about Iron Ridge roof mounts? Personally, I kinda like the
rail design, but the slide in bolt set up seriously sucks.. or Am I
missing something.. again? db <br><br>
