Friends:<br>
<br>
<br>
<br>
I am designing an installation on a roof built with engineered rafters.<br>
These are wood I-beams with 2X4s (or smaller) on flat, dadoed to accept an<br>
OSB flange in between. On top is sheeting and then sheet metal. I have<br>
never attached to engineered rafters<br>
<br>
<br>
<br>
I checked on DPW easy Feet and they look like my best option so far. . Has<br>
anyone else done this before?<br>
<br>
<br>
<br>
Thanks in advance for all the great idea I you professionals are willing to<br>
share.<br>
<br>
<br>
