Hello Wrenches,<br>
<br>
I am looking at a new construction project where the roof will be 5 degree<br>
pitch, 5/8" OSB on top of TJI (truss joists). I am not sure the TJI will<br>
support a lag attachment, as we would use with a conventional wood frame<br>
trusses.<br>
<br>
Have any of you run into this, and if so what attachment method did you<br>
use.<br>
<br>
I have attached tow pictures. One of a similar low slope roof which<br>
appears to use Pro Solar rails and perhaps the Pro Solar Fast Jack<br>
E-series. I'm not sure a single lag would work with the TJI. The other<br>
attached picture is of the TJI. Looking at this amkes me think another<br>
connection method might be a better choice.<br>
<br>
With Regards<br>
