Thanks Bill,
The Quick Mount QBase product comes with two 3"x5/16" lag bolts. I plan on
using those.

Jerry,
The only thing I feel compelled to add with your decision would be
dang sure to pre-drill AND I sure wouldn't be putting a 3/8" lag into a TJI
flange, maybe 1/4" Simpson lags? or tech screws?

Bill,
Mineral bitumen roll roofing. 2:12 slope.
Everyone who gave input below, thanks for the suggestions.
I've decided to go with the Quick Mount Q-Base product. It allows you to get
2 lag bolts into the top chord on either side of the OSB web.

We've done roof mount pv on tji's. Our engineer required 4x blocking
installed between the tji rafters that we lag bolted into. You're not allowed
to cut or drill/bolt into the top and bottom cords of the tji's. We also packed
out both sides of the tji plywood webbing prior to installing the blocking. Our
snow loads oftentimes are too high and won't allow me to screw into the plywood
roof deck only.

I have also used the sunmoto mounts with the multiple holes. They are called
the AL shoe I believe. It makes a great alternative to the DPW ez foot which
are very expensive and take forever to receive. We but butal mastic tape on
the back. Just like the ez foot.

Hi All - We tie into TJIs commonly, if you Google "TJI solar" you'll find
manufacturer docs on how to properly lag in.

Dear Wrenches,
I have a customer with a low slope roof supported by TJI beams. Does anyone
have experience permitting and installing on TJIs? I'm curious if
jurisdictions are requiring Structural Engineer stamps.
Since the top chord of the beams is only 1 3/8" thick should we be using
shorter lag bolts for these installations? It also seems that it would be
undesirable to penetrate into the web of the beam.
Any advice would be appreciated here.
Thank you,
Jerry Caldwell
