Did you look at Unirac SunFrame? It uses shared rails and a continuous cap strip. The installers can also set the modules in the rail which is really nice on steep roofs. If you are in a freeze/thaw climate contact me off-line because there’s a subtle thermal contraction consideration to allow for.

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 From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Aram Alexander Sent: Wednesday, October 14, 2015 7:39 PM To: RE-wrenches <re-wrenches@lists.re-wrenches.org<mailto:re-wrenches@lists.re-wrenches.org>> Subject: Re: [RE-wrenches] Racking for Steep Roofs Pro solar will work just fine.

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.
