Thanks for the responses.
I called UniRac and IronRidge who both confirmed they max out at 45°. UniRac said anything over 45° is considered a wall and requires different testing and certification. They said the primary concern is the end clamp which holds the module by friction only. Mid clamps should hold no problem. They suggested getting an engineer to stamp a custom bolted end clamp solution and we should be good.
I’ve been looking for a good excuse to try Snap n Rack…
Thanks,
Garrison

Pro solar will work just fine.

I would suggest calling unirac as it may be a software issue that uou are having but they will confirm eitherway

Wrenches,
Can anyone recommend a flush mount racking system for really steep roofs? I have two projects coming up on 15/12 (~51°) and none of the usual manufacturers we use for flush mounts (IronRidge XR, Unirac SolarMount, Schletter Solo, DPW Powerrail) can handle this apparently…at least according to their design tools and manuals.
Any advice would be much appreciated.
Thanks,
Garrison
