I can see that the TJI manu doesn't want us blowing 3/8" lags through the top chord of their engineered system. On the other hand, it IS designed to have nails and at least deck screws put into it, as that's how the builder attaches the roof decking. It seems that William's measured approach is (as usual) good advice. I think that multiple 1/4" lags with predilled holes might be acceptable, but that would be up to the engineers and AHJ. My issue with the EZ feet is that you are entirely dependent on how well the roof decking was installed. Nails and construction staples don't have great pull out resistance, so I would hope that the builder uses some type of rated screws to attach the decking.<br>
